About this worksheet

What students practice

  • Students find missing legs and hypotenuses of right triangles in two-dimensional situations.
  • Students use right-triangle cross sections to find lengths in three-dimensional objects.
  • Students use perpendicular changes in position to calculate straight-line distances.

How to use

Use after introducing the Pythagorean Theorem. Have students sketch and label each right triangle before calculating; allow calculators for square roots.

Curriculum

Common Core standard covered

8.G.B.7

Use the Pythagorean Theorem to find unknown side lengths of right triangles in real-world and math problems in 2-D and 3-D.

Model Rocket Launch Day: Length Checks

Use right triangles to check equipment and track a launch.

Prepare the Equipment

Use the Pythagorean Theorem. Give exact answers unless a question asks you to round.

Each launch-stand brace forms the hypotenuse of a right triangle. Match each pair of perpendicular leg lengths to its brace length.
  1. Legs: 10 cm and 24 cm
  2. Legs: 16 cm and 30 cm
  3. Legs: 28 cm and 45 cm
  1. A. 34 cm
  2. B. 26 cm
  3. C. 53 cm
2.
A square heat-resistant tile has sides of 6 cm. Which expression gives the exact distance between opposite corners?
