How to find the third side length of an isosceles triangle?

If you have two sides of an isosceles triangle that are equal and the angle between them is 90 degrees, then you can solve the problem of finding the unknown side length by using the Pythagorean Theorem. The Pythagorean Theorem states that the sum of the squares of the two legs of a right triangle equals the square of the hypotenuse. In the figure below, the square of the hypotenuse (the length of the base of the hypotenuse) is

How to find the third side length of an isosceles triangle without calculator?

This is perhaps the most common question asked about triangles. There are numerous ways to solve this problem, one of which is using the Pythagorean Theorem. The Pythagorean Theorem is: a2 + b2 = c2. If you know the legs of an isosceles triangle you can find each of the sides using the Pythagorean Theorem. First, you need to find the base of an isosceles triangle. Use the two legs to measure the base

What is the third side of an isosceles triangle?

There are a few different ways to find the length of the third side of an isosceles triangle. One method of solving this problem is to use the Pythagorean Theorem. First, you need to know the leg lengths of the isosceles triangle. This is easy to figure out, as the two sides that are of equal length should be opposite each other. If you know the length of one leg, you can measure the length of the adjacent leg. Since the legs are
