Front

What is the formula for the area of a circle?

Back

Area = πr², where r is the radius.

Front

What is the value of π (Pi) used in calculations?

Back

Approximately 3.14.

If the radius of a circle is 4 feet, what is its area?

Back

50.24 ft².

Front

What does it mean for two segments to be congruent?

Back

Two segments are congruent if they have the same length.

Front

If segment LM is congruent to segment QP and LM = 12, what is QP?

Back

QP = 12.

Front

What is the definition of complementary angles?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

If Angle A measures 47 degrees, what is its complement?

Back

43 degrees.

Front

What is the definition of supplementary angles?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If the measure of angle Q is (8x - 40) degrees, what is the measure of its supplement?

Back

(220 - 8x) degrees.

Front

What is the definition of a segment in geometry?

Back

A segment is a part of a line that has two endpoints.
