Angle Relationships

Front

What are supplementary angles?

Back

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

Front

Which angles are considered corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

What is the measure of angle 1 if m∠1 = 113 degrees?

Back

m∠1 = 113 degrees.

Front

What are vertical angles?

Back

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

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.

Front

What is the definition of a transversal?

Back

A transversal is a line that crosses at least two other lines.

Front

What is the sum of the measures of angles on a straight line?

Back

The sum of the measures of angles on a straight line is 180 degrees.

Front

What are complementary angles?

Back

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

Front

How do you find the measure of an angle if you know its supplementary angle?

Back

To find the measure of an angle, subtract the measure of its supplementary angle from 180 degrees.
