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-Angled Triangles. A right-angled triangle (also called a right triangle) is a triangle with a right angle (90Â°) in it. The right angled triangle is one of the most useful shapes in all of mathematics! (It is used in the Pythagoras Theorem and Sine, Cosine and Tangent for example). Try it yourself (drag the points): Two Types. There are two types of right angled triangle: Isosceles right-angled triangle. One right angle Two other equal angles always of 45Â° Two equal sides . Scalene right-angled triangle. One right angle Two other unequal angles No equal sides
