what are complementary angles?
Please help!
Thank you!

thank you but do you think you could tell me what it is? My computer just makes me exit off the internet when i go on the website you wrote to go to. If you could, it would really help me.
Two Angles are Complementary if they add up to 90 degrees (a Right Angle).
These two angles (40° and 50°) are Complementary Angles, because they add up to 90°.
Notice that together they make a right angle.
oh i get it thank you!
Great! :-)
You're welcome.
Complementary angles are a pair of angles whose sum is equal to 90 degrees. In other words, when you add the measures of two complementary angles, the result is 90 degrees.
To identify complementary angles, you can follow these steps:
1. Take note of the angles you are given or have to work with.
2. Add the measures of the angles together.
3. If the sum is equal to 90 degrees, then the angles are complementary.
For example, let's say you have two angles: Angle A with a measure of 40 degrees and Angle B with a measure of 50 degrees.
To determine if these angles are complementary, you add their measures together:
Angle A + Angle B = 40 degrees + 50 degrees = 90 degrees.
Since the sum is equal to 90 degrees, we can conclude that Angle A and Angle B are complementary angles.
