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.
A right-angled triangle has one angle measuring 90 degrees. The side opposite this angle is known as the hypotenuse and it is the longest side. Sine and cosine are trigonometric functions of an angle and are the ratios of the lengths of the other two sides to the hypotenuse of a right-angled triangle.
