Complementary angles are two angles that add up to 90 degrees.
You can find these angles in different shapes and situations, like:
Right triangles: In a right triangle, there are two angles that are less than 90 degrees, which are called acute angles. For example, if one angle is 30 degrees, the other angle would be 90 degrees minus 30 degrees, which equals 60 degrees.
Intersecting lines: When two lines cross each other, the angles that are opposite each other (called vertical angles) can sometimes add up to 90 degrees. You can also find pairs of complementary angles next to the right angle.
In a right triangle, 2 out of the 3 angles are complementary. This idea is really important for understanding trigonometry and measuring angles in geometry for 8th graders.
