Geometry Semester 1 Exam Review 2023-2024

Front

What is the formula for the volume of a sphere?

Back

V = (4/3)πr³, where V is the volume and r is the radius.

Front

If a sphere has a volume of 972π, what is the radius?

Back

The radius is 9.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines.

Front

What is the relationship between parallel lines and a transversal?

Back

When a transversal crosses parallel lines, corresponding angles are equal, alternate interior angles are equal, and alternate exterior angles are equal.

Front

What is a rigid transformation?

Back

A transformation that preserves distance and angle measures, such as translation, rotation, and reflection.

Front

Which of the following is NOT a rigid transformation?

Back

Dilation is NOT a rigid transformation.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

How do you find the value of x in a triangle with angles 60°, 80°, and x?

Back

x = 180° - (60° + 80°) = 40°.

Front

What is the definition of supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What is the definition of complementary angles?

Back

Two angles that add up to 90 degrees.
