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

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

Select all that apply

• The Hypotenuse

• Leg A

• Leg B

• The Right Angle

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

Do these 3 side lengths form a right triangle?
13, 80, and 81?

• yes
• no

a = 2.1, b = 7.2,
c = 7.5
Is this a right triangle?

• yes 
• no

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 missing side.

• 11

• 12

• 13

• 14
