Chapter 3 Review

Front

What does it mean for angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is a transversal line?

Back

A transversal is a line that intersects two or more other lines at distinct points.

Front

What are supplementary angles?

Back

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

Front

If angle 5 measures 60 degrees, what is the measure of an angle that is congruent to it?

Back

An angle that is congruent to angle 5 also measures 60 degrees.

Front

How do you solve for a variable in an equation?

Back

To solve for a variable, isolate the variable on one side of the equation using inverse operations.

Front

What is the sum of the measures of supplementary angles?

Back

The sum of the measures of supplementary angles is 180 degrees.

Front

If angle 6 is not congruent to angle 5, what can you say about their measures?

Back

If angle 6 is not congruent to angle 5, then their measures are different.

Front

What is the relationship between parallel lines and a transversal?

Back

When a transversal intersects parallel lines, it creates corresponding angles, alternate interior angles, and alternate exterior angles.

Front

If two angles are complementary, what is the sum of their measures?

Back

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

Front

What is the value of x if angle x and angle 5 are supplementary and angle 5 measures 130 degrees?

Back

x = 50 degrees.
