Angles with Transversal

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are complementary angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What does it mean for points to be collinear?

Back

Collinear points are points that lie on the same straight line.

Front

If angle 1 = 27º, what is the measure of angle 4 if they are corresponding angles?

Back

Angle 4 = 27º (because corresponding angles are equal).

Front

If angle 2 and angle 6 are corresponding angles, what can we say about their measures?

Back

Angle 2 = Angle 6 (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 equal in measure.

Front

If two angles are supplementary, what is the sum of their measures?

Back

The sum of the measures of supplementary angles is 180 degrees.

Front

What is the relationship between alternate exterior angles?

Back

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

Front

If angle 3 = 63º, what is the measure of angle 5 if they are alternate interior angles?

Back

Angle 5 = 63º (because alternate interior angles are equal).
