Angle Pair Relationships

Front

What are angle pair relationships?

Back

Angle pair relationships refer to the various ways angles can relate to each other when two lines intersect, including complementary, supplementary, vertical, and corresponding angles.

Front

Define complementary angles.

Back

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

Front

Define supplementary angles.

Back

Supplementary angles are two angles whose measures add up to 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

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are same side interior angles?

Back

Same side interior angles are angles that lie between two parallel lines on the same side of a transversal. They are supplementary.

Front

If two angles are supplementary and one angle measures 70 degrees, what is the measure of the other angle?

Back

The other angle measures 110 degrees.

Front

If two angles are complementary and one angle measures 30 degrees, what is the measure of the other angle?

Back

The other angle measures 60 degrees.

Front

Solve for x: x + 35 = 90.

Back

x = 55.
