Pythagorean Theorem Basics and Missing Sides

Find the length of the missing side. 

• 17 cm

• 22 cm

• 15 cm

• 13 cm

The Pythagorean Theorem ONLY works on which triangle? 

• obtuse

• scalene

• isosceles

• right

Do the lengths form a right triangle? 6, 8, 10

• yes

• no

What is the relationship between the sides in the Pythagorean Theorem shown?

• a + b = c

• a² + b² = c²

• a² – b² = c²

• a – b = c

Use the Pythagorean Theorem to solve for x.

Find the value of x. Round to the nearest tenth.
