Pythagorean Theorem: Crack the Code

Solve for the missing side length in each of 10 right triangles with Pythagorean Theorem: Crack the Code! After solving each problem, use the answers to crack the code and reveal the punchline to the joke at the bottom of the page! This eighth-grade geometry worksheet will provide learners with essential practice using the Pythagorean theorem to find the missing leg or hypotenuse lengths of a variety of right triangles. Remember: The Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the legs, or a² + b² = c².  You can use this code-breaking worksheet as a fun and helpful way to prepare students to solve real-world and mathematical problems involving right triangles. For more practice with the Pythagorean theorem, students can try the Pythagorean Theorem: Mixed Practice and Pythagorean Theorem: Word Problems worksheets.
