Special right triangles with angles of two 45 degrees and one 90 degrees are known as 45-45-90 triangles. Special isosceles triangles are what we call all 45-45-90 triangles. The 45-45-90 triangle stands out from all other triangles thanks to three special characteristics: the polygon is an isosceles right triangle; the two side lengths and their opposite angles are congruent; and the hypotenuse, or longest side, is equal to the length of either leg multiplied by the square root of two, or √2.
