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

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

This is the same question as "How to find the length of an isosceles triangle with known sides?". An easy way to do this is to add the legs together, square the sum and subtract twice the first leg length. The result will be the length of the third side.

How to find the third side of an isosceles triangle?

To find the length of the unknown side of an isosceles triangle, you simply need to subtract the base length from half the sum of the two known sides. You can do this without doing any complex calculations. If you have two legs that are the same length, then the base will be half the length of the hypotenuse. If you have two legs that are different lengths, then the base will be the longer leg times the square root of two.
