Types of Angle Pairs

Front

What are two angles whose sum is 180 degrees?

Back

Supplementary Angles

Front

What are the pair of angles formed when two parallel lines are crossed by a transversal, located on the inner side of the parallel lines but opposite sides of the transversal?

Back

Alternate Interior Angles

Front

What are the angle pairs formed when a transversal intersects two parallel lines, located on the same side of the transversal?

Back

Corresponding Angles

Front

What are the pair of angles formed by two intersecting lines that are opposite each other and always congruent?

Back

Vertical Angles

Front

What are the pair of angles formed when two parallel lines are crossed by a transversal, located on the outer side of the parallel lines but opposite sides of the transversal?

Back

Alternate Exterior Angles

Front

What is the definition of complementary angles?

Back

Two angles whose sum is 90 degrees.

Front

What are adjacent angles?

Back

Angles that share a common vertex and a common side but do not overlap.

Front

What are linear pairs of angles?

Back

A pair of adjacent angles formed when two lines intersect, which are supplementary.

Front

What are the properties of vertical angles?

Back

Vertical angles are always equal in measure.

Front

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

Back

Corresponding angles are equal.
