# Understanding Supplementary, Complementary, Vertical and Adjacent Angles 7th Grade Math Worksheets

Looking for the best way to teach students about understanding supplementary, complementary, vertical, and adjacent angles?

This premium worksheet bundle contains 10 activities to challenge your students and help them understand supplementary, complementary, vertical, and adjacent angles.

## Definition:

In Geometry, angle defined as a figure formed by the two rays that meet at one common endpoint.

## Summary:

The concept of angles is very important because it is associated in all geometric figures with corners and in all parallel lines crossing each other.

When two straight lines crossed each other, they form pairs of angles. In this worksheet, we will tackle four pairs of angles namely: supplementarycomplementaryvertical and adjacent angles.

SUPPLEMENTARY ANGLES

Supplementary Angles are angles that form a straight line or what we call a linear pair. Linear pair has an angle that measures 180 degrees. Thus, if you have 2 angles that are equal to 180 degrees when added together, you have supplementary angles.

COMPLEMENTARY ANGLES

Complementary angles are angles, as the name itself, complement each others. These are angles that form a corner that measures 90 degrees.

VERTICAL  ANGLES

Vertical Angles are a pair of nonadjacent angles formed by two lines crossing each other.
