Complementary Angles: Best Buddy Angles!
Imagine two angles that are like best friends who always add up to 90 degrees. We call these "Complementary Angles"!
What Are Complementary Angles?
Two angles that, when put together, make a perfect right angle
They always add up to exactly 90 degrees
Like puzzle pieces that fit perfectly together
Fun Way to Understand
Think of complementary angles like:

10° and 80° are complementary angles (10 + 80 = 90)
