Angles & Parallel Lines with Transversals

Front

What are corresponding angles?

Back

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

Front

Define 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 are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines on opposite sides of a transversal. 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 always equal in measure.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are complementary angles?

Back

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

Front

If angle 1 is 70 degrees, what is the measure of its corresponding angle?

Back

The measure of the corresponding angle is also 70 degrees.

Front

If angle 2 is 45 degrees, what is the measure of its alternate interior angle?

Back

The measure of the alternate interior angle is also 45 degrees.

Front

Determine if the angles are complementary, supplementary, or neither: 30 degrees and 50 degrees.

Back

They are supplementary because 30 + 50 = 80 degrees.

Front

Determine if the angles are complementary, supplementary, or neither: 60 degrees and 30 degrees.

Back

They are complementary because 60 + 30 = 90 degrees.
