Answer:

Step-by-step explanation:

Pythagorean theorem works for right triangles a²+b² = c²

The Pythagorean theorem might be easier to understand written like this ......

(side 1)² + (side 2)² = (hypotenuse)² hypotenuse is c in this diagram

it can also be written like this just flipping both sides (they are still equal)

(hypotenuse)² = (side 1)² + (side 2)²

using algebra to solve for the hypotenuse

hypotenuse = √[ (side 1)² + (side 2)²] remeber hypotenuse = c

c = √[ (side 1)² + (side 2)²] rewritten with c instead of hypotenuse

= √[ 4² + 3² ]

= √( 16 + 9 ]

= √(25)

What number is the square root of 25?

Or what number times itself equals 25?

Your chooses were ...... A B C or D

A 5x5 = ?

B 7x7 = ?

C 16x16 = ?

D 15x15 = ?
