8th grade math worksheet: find ten missing sides, then use a letter code table to answer a riddle about an adorable angle. Answer key included. Part of our using the Pythagorean theorem collection. Aligned to Common Core standards.

How do I use this worksheet?

Start with the reference sheet and the hypotenuse and leg drills, then move to mixed practice and word problems. Use the proof and converse sheets to deepen understanding, and the code breaker for review.

What students will practice

  • Students will find missing legs and hypotenuses in ten right triangles.
  • Students will match each answer to a letter in a code table.
  • Students will check their work by spelling the answer to a riddle.

How do I use this using the Pythagorean theorem worksheet?

Start with the reference sheet and the hypotenuse and leg drills, then move to mixed practice and word problems. Use the proof and converse sheets to deepen understanding, and the code breaker for review.

What does this worksheet teach?

⌄

Find ten missing sides, then use a letter code table to answer a riddle about an adorable angle. The directions on the page read: Find each x and show your work. Find x in the code table on page 2 and write its letter in the blank with the same number to answer the riddle. An answer key is included.

Can I use this using the Pythagorean theorem worksheet for homeschool or classroom?

⌄

Yes, both. We made it for 8th grade Pythagorean theorem, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

How do you find the hypotenuse of a right triangle?

⌄

Square both legs, add them and take the square root. With legs of 12 ft and 5 ft, 144 + 25 = 169, so the hypotenuse is 13 ft. Pythagorean Theorem, Find the Hypotenuse has eight triangles.

What is a Pythagorean triple?

⌄

It is a set of three whole numbers that fit a² + b² = c², such as 8, 15, 17. Multiples of a triple, like 9, 12, 15, are triples too. Pythagorean Triples, Spot and Scale Them asks students to test twelve sets.

How can you prove the Pythagorean theorem?

⌄

One proof places four copies of a right triangle inside a square with side a + b in two ways. Setting the two area expressions equal leaves a² + b² = c². Prove the Pythagorean Theorem With Square Areas guides each step.

How do you use the Pythagorean theorem in three dimensions?

⌄

Find the diagonal of the bottom face first, then use it as a leg with the height to find the space diagonal. Pythagorean Theorem in Three Dimensions practices this with boxes and a cone.
