All triangles have a total of 180 degrees.

The internal angles of any triangle add up to 180 degrees.

Therefore, a RIGHT triangle's angle's added together equal 180 degrees.

The Right Angle = 90 degrees + the other 2 angles total 90 degrees, making the total number of degrees in a Right Angle Triangle = 180 degrees.
