Question

Anjeli writes the equation (a+b)2=c2+4(12ab) to begin a proof of the Pythagorean theorem. Use the drop-down menus to explain why this is a true equation.

Answer 1

(a+b)^2 and c^2+4(1/2ab)

Explanation:

hope that helps!!

Answer 2

Explanation:

`c^(2) = a^(2) + b^(2)`

Red area =
`c^(2)`

One blue triangle = ( a * b *
`(1)/(2)` )

Blue area = 4 * ( a * b *
`(1)/(2)` )

Totally area =
`(a+b)^(2)`

Red area + blue area = totally area

`c^(2)` + 4 * ( a * b *
`(1)/(2)` ) =
`(a+b)^(2)`
