Pythagoras equation for leg or hypotenuse

Teaching Transcript

🎙️

Let's solve the Pythagorean equation for either the leg or the hypotenuse

First we need to know which we are dealing with. If the squared terms are added, that's the leg side.

For the leg side, we can isolate the variable, and then square and simplify

Now you can take the square root of both sides. 'A' will be root 9, or 3. 'C' is root 25, or 5

This math skill teaches solving the Pythagorean equation to find either a leg or the hypotenuse of a right triangle. It explains how to set up the equation, isolate the variable, and use squaring and square roots to find the solution.
