Identify Hypotenuse and Legs of Right Triangles

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

The Pythagorean Theorem ONLY works on which triangle? 

• obtuse
• scalene
• isosceles
• right

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

What is the opposite of squaring a number?

• divide
• multiply 
• fractions
• square root

All of the a square plus all of the b square will perfectly fill the c square with nothing left over.

• True

• False

For this triangle, which side is A, B, and C?

• A = 9 B = 15 C = 12

• A = 9 B = 12 C = 15

• A = 15 B = 12 C = 9

• A = 15 B = 9 C = 12

For this triangle, which side is A, B, and C?

• A = 56 B = 65 C = 33

• A = 65 B = 33 C = 56

• A = 65 B = 56 C = 33

• A = 33 B = 56 C = 65

Which equation correctly represents this right triangle?

• 56² + 65² = 33²

• 33² + 56² = 65²

• 5² + 33² = 56²

• 33² − 56² = 65²
