Can You Make a Right Triangle? Converse of the Pythagorean Theorem

Can you determine whether a triangle is a right triangle just from the side lengths? You can with the converse of the Pythagorean theorem! Featuring a brief explanation and an example problem, this worksheet shows eighth-grade learners how to plug given side lengths into the Pythagorean theorem to determine if the side lengths make up a right triangle. Students will read descriptions of 8 different triangles’ side lengths and use the formula a² + b² = c² to indicate whether each triangle is a right triangle. For more practice with this skill, give students the Converse of the Pythagorean Theorem: Is It a Right Triangle? worksheet next!
