How to find the length of the third side of a triangle calculator?

Using a calculator is the fastest way to find the length of the hypotenuse of a triangle with sides given. If you don’t have a calculator handy, divide each length by its own square root to find the length of the hypotenuse. If you are trying to divide by zero and get an error message, put a number in the denominator larger than the smallest possible hypotenuse length.

There are a few different ways you can program a calculator to find the length of the third side of a triangle. If you know the length of two sides of the triangle, you can use Pythagorean Theorem to solve for the length of the third side. This is the most common method, though it’s not that complicated. If you know the length of two sides of the triangle, you can use the Pythagorean Theorem to find the length of the remaining side of the

How to find the length of the third side of a triangle with unknown angles and sides?

If you know the length of two sides of a triangle, but you don't know the angles, this is an impossible problem. However, there is a way to find the length of the remaining side. If you know the area of a triangle (base × height/perimeter), you can use Pythagorean Theorem (the length of the hypotenuse equals the square root of the sum of squares of the other two sides) to find the missing length.

How to find the length of the third side of a triangle with unknown sides?

Much like solving a right-angled triangle, using the Pythagorean theorem is the easiest way for finding the length of the third side of a triangle with unknown sides. The Pythagorean theorem states that the length of the hypotenuse of a right triangle is equal to the square root of the sum of the squares of the two shorter sides.

How to find the length of the third side of a triangle with unknown angles?

Sometimes we are given the length of the sides of a triangle and the angles of the triangle, but we don’t know the side lengths (e.g., a surveyor’s triangle, which shows the length of a property line), and thus don’t know the angles. In those cases, you can use the Pythagorean Theorem (PT) to find the length of the remaining unknown side.
