Given: m = m



Prove:

Answer 1

prove: ab=cd

`((3)/(5))^2 = (9)/(25)`

Explanation:

It is difficult to find length that way because you still need that extra step where are apply the Pythagorean Theorem (a^2 + b^2 = c^2, where c is the hypotenuse and a and b are the legs), which could use a lot of useless squaring, when you could do something clever instead.
