8th Final - Transversal Angles And Triangle Theorems

Front

What are 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. They are equal in measure.

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.

What is the relationship between the angles in a right triangle?

Back

In a right triangle, one angle is 90 degrees, and the sum of the other two angles is 90 degrees.

What are vertical angles?

Back

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

How do you find the measure of an unknown angle when given two angles?

Back

To find the measure of an unknown angle, use the fact that the sum of angles in a triangle is 180 degrees or that supplementary angles add up to 180 degrees.

Front

What are the properties of parallel lines cut by a transversal?

Back

When parallel lines are cut by a transversal, several angle relationships are formed, including alternate interior angles, alternate exterior angles, corresponding angles, and consecutive interior angles.

Front

What is the measure of angle 1 if angle 2 is 70 degrees and they are corresponding angles?

Back

Angle 1 is also 70 degrees because corresponding angles are equal.

Front

If two angles are supplementary, what is their relationship?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.
