Chapter 3 Review

Front

What is the measure of complementary angles?

Back

Complementary angles always add up to 90 degrees.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

If angle 4 is 45 degrees, what is the measure of its corresponding angle?

Back

The corresponding angle to angle 4 is angle 8, which is also 45 degrees.

Front

What is the measure of angle 6 if it is given as 45 degrees?

Back

The measure of angle 6 is 45 degrees.

Front

How do you find the measure of an indicated angle in a geometric figure?

Back

To find the measure of an indicated angle, use the properties of angles (like complementary, supplementary, or vertical angles) and any given measurements.

Front

What is the relationship between angles 5 and 8 if they are vertical angles?

Back

Angles 5 and 8 are equal in measure.

Front

What is the sum of the measures of two angles that are complementary?

Back

The sum of the measures of two complementary angles is 90 degrees.

Front

How can you identify corresponding angles in parallel lines cut by a transversal?

Back

Corresponding angles are located in the same position at each intersection of the transversal with the parallel lines.

Front

What is the measure of angle 8 if angle 5 is 45 degrees and they are vertical angles?

Back

The measure of angle 8 is also 45 degrees.

Front

What is the definition of supplementary angles?

Back

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