Supplementary Angles
Two Angles are Supplementary if they add up to 180 degrees.

These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°.

Notice that together they make a straight angle.

oh okay thank you i just realized that i can just tyoe it in instead. Thank you for helping me. I would like to ask, you are so good at helping students why don't you teach anymore?

I don't teach any more (for pay) because I retire after 32 years of teaching. That's enough, don't you think? <g>

Besides, I'm now 77 years old.
