Other than the diagonal side of the right triangle, the other two sides make a perpendicular right angle triangle. Other than the diagonal side of the right triangle, the other two sides make a perpendicular right angle triangle. The right angle is 90 degrees.  The right angle is 90 degrees.
Right triangle: A right triangle is one in which one of the angles is a right angle (exactly 90Â°). It is not hard to see that every triangle falls into exactly one of these three groups. Every triangle is either an acute triangle, an obtuse triangle, or a right triangle. Another way to group triangles is by looking at the lengths of their sides: Equilateral triangle: An equilateral triangle is one in which all three sides have the same length. Isoceles triangle: An isoceles triangle is one in which two sides have the same length. Scalene triangle: A scalene triangle is one in which all three sides have different lengths.
