What angles make a triangle? Like, I know 180 is one, but is that it?

A 90 degree angle, 60 degree angle, and a 30 degrre angle

The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees ... The two sides of the triangle that are by the right angle are called the legs ... and the side opposite of the right angle is called the hypotenuse.
