What is a 45-45-90 triangle?

Back

A 45-45-90 triangle is an isosceles right triangle where the angles are 45 degrees, 45 degrees, and 90 degrees. The legs are of equal length, and the hypotenuse is √2 times the length of a leg.

What is the relationship between the legs and the hypotenuse in a 45-45-90 triangle?

Back

In a 45-45-90 triangle, if the length of each leg is 'a', then the length of the hypotenuse 'c' is given by the formula: c = a√2.
