Geometry Final Review #1

Front

What is a point in geometry?

Back

A point is a specific location in space that has no size, dimension, or area. It is usually represented by a dot and labeled with a capital letter.

Front

Define a line segment.

Back

A line segment is a part of a line that is bounded by two distinct endpoints. It has a definite length.

Front

What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions and has no endpoints, while a line segment has two endpoints and a definite length.

Front

What is a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Front

Define an angle.

Back

An angle is formed by two rays that share a common endpoint, called the vertex. It is measured in degrees.

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is a triangle?

Back

A triangle is a polygon with three edges and three vertices. The sum of the interior angles of a triangle is always 180 degrees.

Front

Define a right triangle.

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides (a² + b² = c²).
