Complementary angles are two angles that add up to 90 degrees. Understanding these angles helps us learn more about right angles in geometry.

Here are some key points:

1. Right Angle Definition: A right angle is exactly 90 degrees. This is important to know because it helps us understand what complementary angles are.

2. Angle Relationships:

   • For example, if angle A is 30 degrees, then angle B, which is its complement, would be 60 degrees.
   • Knowing this helps us to see how angles work together and allows us to create different shapes using right angles.

In short, complementary angles help us understand right angles better. This knowledge is essential for making different designs and solving geometry problems.
