Question

Is it possible to draw a triangle whose angles measure 50°, 50°, and 80°?

Answer 1

First of all, we know a quality of all interior angles of a triangle, they should add to 180 degrees. 

Does 50+50+80 degrees give 180 degrees? 

100+80=180 degrees 

Therefore, yes, it is possible to draw a triangle with the angle measures given to be 50, 50 and 80 degrees. 

Hope I helped :)
