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.
