Answer:
prove: ab=cd
[tex](\frac{3}{5})^2 = \frac{9}{25}[/tex]
Step-by-step 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.
