Question

Which of the following is the correct equation for the Pythagorean Theorem, where a and b are the side lengths and c is the length of the hypotenuse?

A. a^2-b^2=c^2
B. (a+b)^2=c^2
C.(a-b)^2=c^2
D. a^2+b^2=c^2

Answer 1

`\huge \boxed{ \mathrm{D.} \ \ a^2 +b^2 =c^2}}`

Explanation:

The correct equation for the Pythagorean theorem is:

`\Rightarrow \ \ a^2 +b^2 =c^2`

c is the length of the hypotenuse of the right triangle

a and b are the side lengths of the right triangle
