Look at the blue lines of the triangle. The lines both intersect each other at a 90 degree or right angle. These lines are the legs of the triangle. The leg of a triangle is one of the sides that make up the right angle in a right triangle.
The orange line is not the leg of the triangle. Instead, it is the hypotenuse. The hypotenuse of a right triangle is the side opposite of the right angle. It is also the longest side of the triangle.
Once you know the sides of the triangle, you can plug in the numbers to the Pythagorean theorem. The Pythagorean theorem is the relationship of the lengths the sides of a right triangle. The formula is in blue and orange to help you know where the sides go in the equation. Let’s try an example:
