A right-angled triangle is a polygon of three sides having one angle as 90 degrees(right angle).
In a right-angled triangle, the side opposite to the right angle is always bigger than the other two sides.
This bigger side is called Hypotenuse, the side on which the triangle rests is called base or adjacent and the third side is called height or perpendicular.
Hence, the proof of the triangle is right triangle is given by ''use the distance formula to see if all three sides are congruent''.
