• 18 km

solve for c

• 7

• 9

• 4

• 13

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

• a + b = c

• a² + b² = c²

• a² – b² = c²

• a – b = c

Which Pythagorean Triple does the picture illustrate?

• 4, 5, 6

• 2, 3, 4

• 3, 4, 5

• 1, 2, 3

The Pythagorean Theorem ONLY works on which triangle? 

• obtuse

• scalene

• isosceles

• right

Which equation reflects the right triangle shown?

• x² + 14² = 20²

• 14² + 20² = x²

• 14² – 20² = x²

• x² – 14² = 20²

If a = 8 and c = 10, what is the area of square B?

• 6

• 164

• 36

Which equation can NOT be used to find the length of the missing side?

• 12² + 13² = x²

• x² + 12² = 13²

• 13² – 12² = x²

• 13² – x² = 12²
