A point represents an exact location in space without any dimensions. It does not have length, width, or height, making it a fundamental concept in geometry.

A line is an infinitely extending one-dimensional figure with no curvature and no thickness. This basic concept is essential for understanding more complex geometric ideas.

An angle is created when two rays meet at a common endpoint. Its measure indicates the amount of rotation between the two rays.

A segment is a portion of a line with two fixed endpoints, which gives it a measurable length. Unlike a full line, a segment does not extend infinitely.

A ray has one fixed endpoint and continues endlessly in one direction. This characteristic distinguishes it clearly from a full line.

Supplementary angles are defined as two angles whose measures sum to 180 degrees. This property is often used to determine unknown angle measures in geometric figures.

An isosceles triangle is one where exactly two sides are equal in length. While an equilateral triangle has all sides equal, the specific condition of having two equal sides defines an isosceles triangle.

The interior angles of any triangle always add up to 180 degrees. This fundamental rule is used frequently to solve for unknown angles in triangles.

The sum of the interior angles in any quadrilateral is 360 degrees. This is a consistent property that holds true for all four-sided figures.

A line parallel to the x-axis is horizontal, which means there is no vertical change as you move along the line. Therefore, its slope is 0.

A regular polygon is one in which all sides and interior angles are equal. This uniformity distinguishes it from irregular, concave, or cyclic polygons.

Complementary angles are two angles whose measures sum to 90 degrees. This distinguishes them from supplementary angles, which total 180 degrees.

The area of a rectangle is found by multiplying its length by its width. This straightforward formula is a basic component of area calculation in geometry.

Congruent figures are exactly the same in both shape and size. This means every corresponding side and angle is identical between the figures.

The radius is defined as the line segment from the center of a circle to any point on its circumference. All radii in a circle are equal in length, making it a key concept in circle geometry.

By applying the Pythagorean theorem, the hypotenuse is calculated as √(3² + 4²) = √(9 + 16) = √25, which equals 5. This is a classic example of a Pythagorean triple.

Similar triangles not only have equal corresponding angles but also maintain a constant ratio between the lengths of their corresponding sides. This proportionality is a key characteristic used in many geometric proofs and calculations.

The fraction of the circle's circumference subtended by a central angle is determined by dividing the angle by 360 degrees. Since 60 divided by 360 simplifies to 1/6, the correct answer is 1/6.

Alternate interior angles are congruent when a transversal cuts across two parallel lines. This fundamental property is widely used in geometry to prove angle relationships.

In dilation, the area of a shape is multiplied by the square of the scale factor. With a scale factor of 3, the area increases by 3², which is 9 times the original area.
