# Complementary and Supplementary Angles 7th Grade Worksheet (with answer key + pdf)

If the sum of measure of two angles is equal to 90 degrees, it is called complementary angle. And if the sum of measure of two angles is equal to 180 degrees, it is called supplementary angle. If one of the angles that make complementary or supplementary angles is known, we can find the other angle.

## What is the “Complementary and Supplementary Angles 7th Grade Worksheet (pdf)”?

The Complementary and Supplementary Angles 7th Grade Worksheet (pdf) includes various exercises to understand the concept of complementary and supplementary angles. This worksheet is designed to enable learners to learn about how we can find the complement of an angle i.e., if one angle is known how can we find the other angle that makes a complementary or supplementary angle and if two angles are given, how can we figure out if the angles are complementary or supplementary angles.

Since this worksheet is designed to have many maths drill; solved examples and practice problems, therefore, it will help learners grasp the concept clearly. It also has a reflection and evaluation section along with a challenge that will help learners construct their own word problem and solve it.

## Instructions on how to use the “Sets for Class 11 Worksheet (with answers)”?

First, learn the concepts of complementary and supplementary angles through examples done in the first section and then practice problems given in the “Applying” section of this worksheet.

A reflective section at the end of the worksheet is provided to help the learner reflect his own thinking and assess how they performed in the lesson.

Lastly, the learner has to design his own method of doing complementary and supplementary angles problems.

## Conclusion

This worksheet explains the concept of how we can find the complement of an angle via examples and practice problems and how we can figure out if the angles are complementary or supplementary. It will help you understand how we can use these concepts to solve world problems effectively.
