Front

What are vertical angles?

Back

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

Back

The corresponding angle to angle 4 is angle 8.

Front

What is the relationship between angle 1 and angle 4 if they are vertical angles?

Back

Angle 1 and angle 4 are congruent.

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 lines. They are congruent.

Back

Angle 6 is NOT congruent to angle 5.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal. They are congruent.
