Determine If Side Lengths Represent a Right Triangle

The Pythagorean Theorem ONLY works on which triangle? 

• obtuse
• scalene
• isosceles
• right

The legs of a right triangle are represented by a and b, and the hypotenuse of the right triangle is represented by c. Which equation represents the Pythagorean Theorem?

• a² + b² = c²

• a² + c² = b²

• a + b = c

Sides a and b are called legs.

• true

• false

What is the name for side c?

• head

• body

• hippopotamus

• hypotenuse

Side c on a right triangle is ALWAYS the longest.

• true

• false

Do the segment lengths 15, 12, and 9 form a right triangle?

• Yes
• No
• Maybe
• Pythagoras

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

• Leg

• a

• Hypotenuse

• Obtuse

Which is the formula used for the Pythagorean Theorem?

• a²+b²+c²

• a+b=c

• a²+c²=b²

• a²+b²=c²

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

a=3, b=4, and c=5

Is this a right triangle?

• yes

• no
