Which shape has three sides and three angles?
Triangle
Square
Rectangle
Circle
A triangle is a three-sided polygon with three vertices and three angles. This shape is the simplest polygon that meets the description.
Which shape has four equal sides and four right angles?
Square
Rectangle
Rhombus
Trapezoid
A square is characterized by having four equal sides and four 90-degree angles. This distinguishes it from other quadrilaterals where side lengths may vary.
Which shape is round and has no straight edges or vertices?
Circle
Ellipse
Oval
Polygon
A circle is defined by a continuously curved line where every point is equidistant from the center. It has no vertices or straight edges, unlike other shapes.
What is a closed figure with straight sides called?
Polygon
Arc
Curve
Line
A polygon is a closed figure made up of straight line segments. Examples include triangles, rectangles, and other multi-sided figures.
What is the sum of the interior angles of a triangle?
180 degrees
90 degrees
360 degrees
270 degrees
Every triangle's interior angles always add up to 180 degrees. This is a fundamental property in geometry.
What is the perimeter of a rectangle with a length of 8 cm and a width of 3 cm?
22 cm
24 cm
11 cm
16 cm
The perimeter of a rectangle is calculated as 2 × (length + width). For this rectangle, 2 × (8 + 3) equals 22 cm.
Which quadrilateral has only one pair of parallel sides?
Trapezoid
Square
Rectangle
Parallelogram
A trapezoid is defined as having just one pair of parallel sides. The other listed quadrilaterals have two pairs of parallel sides.
What is the sum of the interior angles of a quadrilateral?
360 degrees
180 degrees
270 degrees
90 degrees
The sum of interior angles in any quadrilateral is 360 degrees. This can be seen by dividing the quadrilateral into two triangles.
How many lines of symmetry does a regular hexagon have?
6
3
4
2
A regular hexagon has 6 equal sides, resulting in 6 lines of symmetry. Each line of symmetry divides the hexagon into mirror-image halves.
Which term best describes a polygon with all sides and angles equal?
Regular polygon
Irregular polygon
Concave polygon
Scalene polygon
A regular polygon has both equal sides and equal angles. This uniformity makes it highly symmetrical when compared to irregular polygons.
In a parallelogram, what is always true about opposite sides?
They are equal in length
They are perpendicular
They are not parallel
They are equal to the diagonals
Opposite sides in a parallelogram are both parallel and equal in length. This is one of the defining properties of parallelograms.
How many degrees is each interior angle of a regular octagon?
135 degrees
120 degrees
140 degrees
150 degrees
A regular octagon's interior angles sum to (8-2)×180 = 1080 degrees. Dividing 1080 by 8 gives 135 degrees per angle.
Which triangle has exactly two equal sides?
Isosceles triangle
Equilateral triangle
Scalene triangle
Right triangle
An isosceles triangle has exactly two sides of equal length. In contrast, an equilateral triangle has all sides equal, and a scalene triangle has no equal sides.
In a circle, what is the term for a segment that passes through the center with endpoints on the circle?
Diameter
Radius
Chord
Arc
The diameter is the longest chord in a circle and passes through the center. It is exactly twice the length of the radius.
What is the formula to find the area of a rectangle?
Length × Width
2 × (Length + Width)
Length + Width
2 × Length × Width
The area of a rectangle is found by multiplying its length by its width. This is one of the most basic formulas in geometry.
Which characteristic defines a square?
It has four equal sides and four right angles
It has two pairs of equal sides but no right angles
It has unequal sides and one pair of parallel sides
It has curved edges
A square is defined by its four equal sides and four right angles. This makes it a special form of both a rectangle and a regular quadrilateral.
What is the measure of each exterior angle of a regular pentagon?
72 degrees
60 degrees
90 degrees
108 degrees
The sum of exterior angles in any polygon is always 360 degrees. Dividing 360 by the 5 sides of a pentagon yields 72 degrees per exterior angle.
Which formula correctly calculates the circumference of a circle?
2 × π × r
π × r^2
π × d^2
2 × r
The circumference of a circle is given by 2 × π × r, where r is the radius. This formula measures the distance around the circle accurately.
Which shape is defined as all points in a plane equidistant from a given central point?
Circle
Ellipse
Square
Polygon
A circle is the set of all points in a plane that are a fixed distance from a central point. This definition distinguishes a circle from other shapes.
If a rectangle has a perimeter of 20 cm and a length of 7 cm, what is its width?
3 cm
5 cm
7 cm
10 cm
The perimeter of a rectangle is calculated as 2 × (length + width). With a perimeter of 20 cm and a length of 7 cm, solving 2 × (7 + width) = 20 gives a width of 3 cm.
