The length of the third side of the triangle can be calculated using Pythagoras' theorem. \[c^2 = a^2 + b^2\] … WebIn a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle. cygwin evince https://bdmi-ce.com
