Pythagorean Theorem

The Pythagorean Theorem ONLY works on which triangle?

• Obtuse

• Scalene

• Right

• Isosceles

The longest side of a right triangle is DIRECTLY ACROSS from the:

• Right angle

• Acute angle

• Obtuse Angle

If a right triangle has side lengths 6, 6.7 and 3, which side is the hypotenuse?

• 6

• 6.7

• 3

• 15.7

• None of the above.

In a right triangle, if a = 8 and c = 17, what is the correct setup to find the value of b?

• $17^2+8^2=b^2$

• $8^2+b^2=17^2$

• $17^2+b^2=8^2$

• $\frac{8^2}{b^2}=\frac{17^2}{100}$

Which set of sides would make a right triangle?

• 4, 5, 6
• 8, 10, 12
• 5, 12, 13
• 5, 10, 12

What is the final step in solving this work for c?

a² + b² = c²

3² + 4² = c²

9 + 16 = c²

25 = c²

• Divide both sides by 2

• Take the square root of both sides

solve for c

• 7
• 9
• 4
• 13

_{^{Find the missing side}}

• 9
• 41
• 6.4
• 3
