What happens to a shape when it undergoes a rotation transformation?
It flips over an axis
It shifts location without turning
It changes its size
It turns around a fixed point
Rotation moves every point of a shape along a circular arc around a fixed point. This transformation changes the orientation but preserves the size and shape of the figure.
A square is rotated 90° clockwise about its center. Which statement is true about the square?
It shifts position without rotating
It becomes a different shape
Its orientation changes while its size remains unchanged
Its size increases
A 90° rotation changes the square's orientation but does not affect its size or shape. The square remains congruent to its original form after the rotation.
What rotation angle will always return a shape to its original position?
360°
90°
45°
180°
A complete 360° rotation brings a shape back to its starting orientation. Partial rotations do not result in the original position except in special cases of symmetry.
In a rotation transformation, what is the center of rotation?
The midpoint of the longest side
The fixed point around which the shape spins
The intersection of the shape's diagonals
A point chosen at random on the shape
The center of rotation is the point that remains stationary while other points of the shape move along circular paths. This fixed point is essential in determining the angle and effect of the rotation.
Which transformation rotates a figure around a fixed point without altering its size or shape?
Rotation
Reflection
Dilation
Translation
Rotation turns a figure about a fixed point while keeping its congruence intact. This means that while the orientation of the shape changes, its size and shape remain the same.
What are the coordinates of the point (3, 2) after a 90° counterclockwise rotation about the origin?
(3, 2)
(-3, -2)
(2, -3)
(-2, 3)
Using the rotation formula for 90° counterclockwise, (x, y) transforms to (-y, x). Therefore, (3, 2) becomes (-2, 3). This maintains the distance from the origin while changing the point's direction.
Which rotation transforms the point (-4, 5) into (-5, -4)?
270° counterclockwise
90° counterclockwise
90° clockwise
180°
The rotation formula for 90° counterclockwise converts (x, y) to (-y, x), so applying it to (-4, 5) yields (-5, -4). This confirms that the correct transformation is a 90° counterclockwise rotation.
A 270° clockwise rotation of a shape about the origin is equivalent to which counterclockwise rotation?
180° counterclockwise
360° counterclockwise
90° counterclockwise
270° counterclockwise
Since a full rotation is 360°, a 270° clockwise rotation leaves a remainder of 90° when compared with 360°. Thus, it is equivalent to a 90° counterclockwise rotation.
After a 180° rotation about the origin, what are the new coordinates of the vertex (1,2) from the triangle with vertices (1,2), (3,2), and (2,4)?
(-1, 2)
(1, -2)
(-1, -2)
(-2, -1)
A 180° rotation about the origin sends any point (x, y) to (-x, -y); thus, (1,2) becomes (-1,-2). This transformation preserves the distances between points.
Which property of a geometric figure is preserved after a rotation?
Size and shape
Orientation
Color and texture
Distance from the center of rotation
Rotation is a type of congruence transformation that preserves the size and shape of a figure. While the figure's orientation may change, its dimensions remain constant.
When a regular pentagon is rotated 72° about its center, what happens?
It becomes an irregular pentagon
It fits exactly over its original position
It shifts to a completely new position
It appears as a mirror image of the original
A regular pentagon has a rotational symmetry of 72°, meaning that a rotation by that angle maps the pentagon onto itself. This property is a characteristic of all regular polygons.
Which of the following best describes rotational symmetry in a figure?
It remains identical after a reflection over a line
It enlarges proportionally after a dilation
It looks the same after a rotation by an angle less than 360°
It maintains its position after being translated
Rotational symmetry means that a figure looks identical after being rotated by a certain angle that is less than 360°. This distinctive property does not apply to other transformations like reflection or dilation.
What is the correct transformation rule for rotating a point (x, y) 90° clockwise on the coordinate plane?
(x, y) â†' (-x, y)
(x, y) â†' (-y, x)
(x, y) â†' (y, -x)
(x, y) â†' (-x, -y)
In a 90° clockwise rotation, each point is mapped from (x, y) to (y, -x). This formula is derived from the definitions of rotational transformations in the coordinate plane.
When a rectangle is rotated 45° about its center, which of its characteristics is altered?
Parallelism of opposite sides
Area
Orientation
Side lengths
Rotating a figure changes its orientation but leaves other properties like area, side lengths, and parallelism unchanged. This is because rotation is a rigid motion that preserves the shape and size.
What are the coordinates of the point (6, -3) after a 270° counterclockwise rotation around the origin?
(3, 6)
(-6, 3)
(3, -6)
(-3, -6)
A 270° counterclockwise rotation is equivalent to a 90° clockwise rotation, and using the rule (x, y) â†' (y, -x) gives (-3, -6) for the point (6, -3). This transformation preserves distances from the origin.
If a figure is rotated about a point that is not its center of symmetry, what typically occurs?
It changes its size and shape
It becomes a mirror image of the original
It usually does not align with its original position except with a full 360° rotation
It always aligns perfectly with its original position
Rotating about a point different from the center of symmetry means the figure's position relative to its original orientation changes. Only a full 360° rotation will return the figure to its starting alignment.
What composite transformation is equivalent to a 180° rotation about a point?
A reflection over two perpendicular lines that intersect at that point
A translation followed by a reflection
Two consecutive translations
A single reflection over any line
Reflecting a figure over two perpendicular lines that intersect at a point is equivalent to a 180° rotation about that intersection. This composite transformation changes the orientation in the same way as a half-turn rotation.
Why does a regular hexagon map onto itself after a 60° clockwise rotation about its center?
Because its sides are congruent
Because it is symmetric about a line
Because it has 6-fold rotational symmetry
Because its angles are all equal
A regular hexagon has 6-fold rotational symmetry, meaning that rotations of 360°/6 or 60° map the hexagon onto itself. This property ensures that the hexagon remains unchanged in appearance after such rotations.
What is the net effect of rotating a shape 90° and then 270° about the same center?
A rotation of 180°
A reflection
A full 360° rotation, returning the shape to its original position
A translation
Rotations add together, so 90° + 270° equals 360°. A 360° rotation brings the shape back to its initial orientation, effectively resulting in no net change.
How does a rotation affect the distance between any two points of a figure?
The distances remain unchanged
The distances vary with the angle of rotation
The distances increase
The distances decrease
Since rotation is a rigid motion, it preserves the distance between any pair of points within the figure. This invariance ensures that the shape's size and proportions are maintained.

  1. Rotation Basics - Rotation is all about turning a shape around a fixed pivot, called the center of rotation, by a certain angle and direction. It's like spinning your favorite pizza slice on a plate: the slice stays the same size, but it faces a new way! Third Space Learning: Rotations Guide
  2. Key Rotation Angles - Become best friends with 90°, 180°, and 270° rotations - each moves points to predictable new spots. For instance, a 90° clockwise spin sends (x, y) to (y, - x), like turning the hands of a clock. Intellectual Math: 2D Rotation Practice
  3. Clockwise vs. Counterclockwise - Direction matters! Counterclockwise turns are labeled positive and feel like you're marching around a circle to the left, while clockwise moves go the opposite way. Practicing both helps you master any spin. Third Space Learning: Rotation Directions
  4. Trace and Transform - Grab some tracing paper and physically rotate shapes to watch their movements with your own eyes. This tactile trick builds intuition and makes abstract rotations feel like hands-on magic. Third Space Learning: Hands-On Rotations
