Pythagorean Theorem Day #1

What do we call the side across from the right angle?

• Leg

• a

• Hypotenuse

• Obtuse

What is always true about the hypotenuse?

• Is the shortest side of the triangle.

• Is the height of the triangle.

• Is labeled as b.

• Is the longest side of the triangle.

Which is the formula used for the Pythagorean Theorem?

• a²+b²+c²

• a+b=c

• a²+c²=b²

• a²+b²=c²

If the side lengths of a right triangle are 7, 25, and 24, which side is the hypotenuse?

• 7

• 25

• 24

• none of the these

If the sides of a right triangle are 40, 50, and 30, which sides are the legs?

• 40 and 50

• 50 and 30

• 40 and 30

• 30, 40, and 50

The Pythagorean Theorem ONLY works on which triangle? 

• obtuse
• scalene
• isosceles
• right

Do these side lengths form a right triangle? Remember, it doesn't matter what the drawing LOOKS like, it matters if the side lengths prove that it is a right triangle!

• yes

• no

Identify the hypotenuse.

• x
• z
• w

Which equation will help you find the missing side?
