A right triangle has a 90 degree angle in it. This is not to be confused with a wrong triangle, which has two 90 degree angles.
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
90 degree but not just for a triangle it can be 90 degree square or what ever shape you talking about
