Finding Unknown Side Lengths

Open Up Resources 35 min(s)

Apply the Pythagorean Theorem to determine unknown side lengths in right triangles. Let's find missing side lengths of right triangles. Learning targets: When students have a right triangle, they can identify which side is the hypotenuse and which sides are the legs. If students know the lengths of two sides, they can find the length of the third side in a right triangle.
