Understanding Angles Made Simple

It's really important to know about complementary and supplementary angles. This will help you solve angle problems better!

What Are These Angles?

• Complementary Angles: These angles add up to 90 degrees.

  • For example, if one angle is 30 degrees, the other one is 90 - 30 = 60 degrees.

• Supplementary Angles: These angles add up to 180 degrees.

  • So, if one angle is 110 degrees, the other one is 180 - 110 = 70 degrees.

Easy Examples:

1. Complementary Example:

   • If angle A is 45 degrees, then angle B is 90 - 45 = 45 degrees too.

2. Supplementary Example:

   • If angle C is 130 degrees, then angle D is 180 - 130 = 50 degrees.

By understanding these concepts, you can find unknown angles in different shapes and problems!
