2/17 - ANGLE RELATIONSHIPS VOCABULARY PRACTICE

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two parallel lines. They are equal in measure.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are on the same side of the transversal and in corresponding positions relative to the parallel lines. They are equal in measure.

Front

What are vertical angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

What are congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

If angle 4 is 50 degrees, what is the measure of its vertical angle?

Back

Angle 4's vertical angle is also 50 degrees.

Front

If angle 1 is 70 degrees, what is the measure of its corresponding angle?

Back

The corresponding angle (angle 6) is also 70 degrees.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

Alternate interior angles are equal.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal.

Front

What is the sum of the measures of supplementary angles?

Back

The sum is always 180 degrees.
