Vocab Review Transversals and Angles

Front

What is a transversal in geometry?

Back

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

Front

Define alternate interior angles.

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a 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.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

What are vertical angles?

Back

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

Front

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

Back

The measure of an angle's complement can be found by subtracting the angle from 90 degrees.

Front

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

Back

The measure of an angle's supplement can be found by subtracting the angle from 180 degrees.

Front

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

Back

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

Front

If two angles are supplementary, what is their sum?

Back

The sum of two supplementary angles is 180 degrees.

Front

If two angles are complementary, what is their sum?

Back

The sum of two complementary angles is 90 degrees.
