Pythagorean Thm. Review

The Pythagorean Theorem ONLY works on which triangle?

• obtuse

• scalene

• isosceles

• right

What side(s) will always be the longest on a right triangle?

• The Hypotenuse

• Leg A

• Leg B

• The Right Angle

The legs form what type of angle?

• Acute
• Obtuse
• Reflex
• Right

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

Hint: Think about when the hypotenuse is missing!

• a + b = c

• a² + b² = c²

• a² – b² = c²

• a – b = c

Do three squares with side lengths of 6, 12, and 13 form a right triangle?

• Yes
• No

If three sides of a right triangle are 9, 40, and 41, which side is the hypotenuse?

• 9
• 40
• 41

Isabella has sticks that are 10cm, 11cm, and 13cm long.  Can she place the sticks together to form a right triangle?  Justify your answer.

• No, because 10+11 does not equal 13
• No, because 100+121 does not equal 169
• Yes, because there is a small side, medium side and long side
• Yes, because a triangle has 3 sides

Find the length of the missing side. 

• 17 cm
• 22 cm
• 15 cm
• 13 cm

Find the length of the missing side. 

• 25 cm
• 42 cm
• 52 cm
• 48 cm

solve for c

• 7
• 9
• 4
• 13
