# right triangle

#### sri340

The lengths of the sides of a right triangle are consecutive even integers , and the length of the shortest side is a x . which of the following equations could be used to find x ?

(A) x + x + 1 = x + 2
(B) x^2 + (x + 1)^2 = (x + 2)^2
(C) x^2 + (x + 2)^2 = (x + 4)^2
(D) x + x + 2 = x + 4
(E) x^2 = (x + 2)(x + 4)

the lengths of your sides are:
x
x+2
x+4

The hypoteneuse is the always the longest side, use pythagoras' theorum

If you are completely stuck, read the spoiler
Pythagoras' theorum says $$\displaystyle a^2 + b^2 = c^2$$, where c is the hypotenuse.

Apply this as follows:
a = x
b = x+2
c = x+4

$$\displaystyle x^2 + (x+2)^2 = (x+4)^2$$

(E) x^2 = (x + 2)(x + 4)
If the sides are consecutive even integers, then their lengths are

$$\displaystyle x, x + 2, x+ 4$$.

Now what is the extremely well known formula that relates three sides of a right angle triangle?
