Ever notice how some things just *complement* each other perfectly? Like peanut butter and jelly, or sunshine and a cool breeze? Well, angles can be complementary too! In geometry, when we talk about **two angles that add up to 90 degrees**, we call them *complementary angles*.
Think of it like slicing a right angle (that perfect corner!) into two smaller pieces. Each piece is an angle, and together they fill that 90-degree space. So, if you have an angle of 30 degrees, its complementary angle would be 60 degrees (because 30 + 60 = 90).
Knowing about complementary angles is super helpful in geometry and even in everyday life, like when you're building something or figuring out the best angle for a photo! Keep an eye out for these angle pairs – they're all around you!
