Finding Unknown Side Lengths
The purpose of this lesson is to use the Pythagorean Theorem to find unknown side lengths of a right triangle.
- Calculate unknown side lengths of a right triangle by using the Pythagorean Theorem, and explain (orally) the solution method.
- Label the “legs” and “hypotenuse” on a diagram of a right triangle.
Let’s find missing side lengths of right triangles.
- If I know the lengths of two sides, I can find the length of the third side in a right triangle.
- When I have a right triangle, I can identify which side is the hypotenuse and which sides are the legs.
