Front

What are congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

Which angles are considered corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

What is the Alternate Interior Angles Theorem?

Back

The Alternate Interior Angles Theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles is congruent.

Front

Define Alternate Exterior Angles.

Back

Alternate Exterior Angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal.

Front

What is the measure of angle 4 if angle 8 measures 76°?

Back

Angle 4 measures 76° because they are corresponding angles.

Front

What is the relationship between angle 5 and angle 6 if angle 5 is congruent to angle 1?

Back

If angle 5 is congruent to angle 1, then angle 6 is NOT congruent to angle 5.

Front

What are Vertical Angles?

Back

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

Front

How do you find the measure of an angle when given its supplementary angle?

Back

To find the measure of an angle when given its supplementary angle, subtract the measure of the supplementary angle from 180°.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180°.

Front

What is the definition of a transversal?

Back

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