Complementary And Supplementary Angles Worksheet 7th Grade Pdf
As students progress through their mathematics education, they are introduced to new concepts and ideas that build upon their prior knowledge. One important topic that is covered in 7th-grade math is complementary and supplementary angles. These angles play a crucial role in understanding geometry, trigonometry, and algebra. In this article, we’ll explore the complementary and supplementary angles worksheet 7th grade pdf in detail.
What are Complementary Angles?
Complementary angles are a pair of angles whose sum is 90 degrees. This means that when you add the measure of one angle to the measure of its complement, the result is 90 degrees. Complementary angles are often represented as two angles that form an L-shape, with one angle measuring x degrees and the other measuring 90-x degrees.
When solving problems involving complementary angles, you will often be given the measure of one of the angles and asked to find the measure of its complement. For example, if you are given that one angle in a pair of complementary angles is 45 degrees, you can find the measure of its complement by subtracting 45 from 90, which gives you 45 degrees.
What are Supplementary Angles?
Supplementary angles are a pair of angles whose sum is 180 degrees. This means that when you add the measure of one angle to the measure of its supplement, the result is 180 degrees. Supplementary angles are often represented as two angles that form a straight line, with one angle measuring x degrees and the other measuring 180-x degrees.
When solving problems involving supplementary angles, you will often be given the measure of one of the angles and asked to find the measure of its supplement. For example, if you are given that one angle in a pair of supplementary angles is 120 degrees, you can find the measure of its supplement by subtracting 120 from 180, which gives you 60 degrees.

Tips for Solving Complementary and Supplementary Angles Problems
Here are some tips that can help you when solving problems involving complementary and supplementary angles:
- Remember that complementary angles add up to 90 degrees, and supplementary angles add up to 180 degrees.
- When working with complementary angles, you can use the fact that the sum of the two angles is 90 degrees to set up an equation and solve for one of the angles.
- When working with supplementary angles, you can use the fact that the sum of the two angles is 180 degrees to set up an equation and solve for one of the angles.
- Look for relationships between angles. For example, if you are given that two angles are complementary and one of them is x degrees, you know that the other angle is 90-x degrees.
- Draw pictures or diagrams to help you visualize the problem.
