The way to find the missing side of a triangle-THIS ONLY WORKS ON RIGHT ANGLED TRIANGLES-is square both sides seperately and then add them together to give you the square of the missing side-find the square root and that is the size of the missing side-eg. if you have a RIGHT ANGLED TRIANGLE with sides of 3inch and 4inch then (3x3) + (4x4) = 25 so the square root of 25 is 5 meaning the missing side is 5inch.

What is the missing side of the right triangle called?

The missing side of a right triangle is called the hypotenuse. This side is opposite the right angle and is the longest side of the triangle.

How do you find the length to a missing side of a right triangle?

Pythagorean Theorem: a2 + b2= c2 where c is the hypotenuse of a right triangle. Hypotenuse is the side of a right triangle opposite to the right angle.


What is the right triangle if a12 and b13 what is c?

If the 13 is the longest side of that right triangle, then the missing side is 5 . If 'c' is the longest side of that right triangle, then the missing one is 17.692 (rounded).


How do you find a missing side to a right triangle?

A triangle always has 180 units. You would have to add up the two sides and subtract that from 180.
