Module 2 Review: Angles formed by Transversals

Front

What are vertical angles?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are the angles that are in the same position at each intersection where a straight line crosses two others. They are equal.

Front

What are alternate interior angles?

Back

Alternate interior angles are the pairs of angles on opposite sides of the transversal but inside the two lines. They are equal.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are the pairs of angles on opposite sides of the transversal but outside the two lines. They are equal.

Front

What does it mean for angles to be congruent?

Back

Congruent angles are angles that have the same measure.

Front

What does it mean for angles to be supplementary?

Back

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

Front

If Angle 1 and Angle 5 are corresponding angles, what can we say about their measures?

Back

Angle 1 and Angle 5 are equal in measure.

Front

If Angle 6 and Angle 7 are vertical angles, what can we say about their measures?

Back

Angle 6 and Angle 7 are equal in measure.

Front

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

Back

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

Front

If Angle 4 and Angle 6 are congruent, what does that imply?

Back

It implies that Angle 4 and Angle 6 have the same measure.
