Right Triangle Check with Converse

You’ve learned the Pythagorean Theorem—but can you use it in reverse? This playsheet helps you apply the converse of the theorem to check whether a triangle is right-angled. It’s a smart way to test your math knowledge while boosting real-world thinking.
 

You’ll work with sets of three side lengths, square the shorter sides, and see if their sum matches the square of the longest side. If it does—you’ve got a right triangle! Each check helps you build strong problem-solving habits and confidence in your reasoning.
 

You get to practice comparing numbers, recognizing patterns, and organizing your work clearly. These exercises don’t just test your math—they help you develop accuracy and precision, skills that matter in every subject.
