show that EF and KL have the same length, using the Distance Formula.
I know that the distance formula is but how do i do this problem i mean how do i know what letter is x1, x2, y1, or y2. help me please. but explain it to me too.

Do you know what the co-ordinates of e, f, k and l are? E.g. say e is (1, 3) and f is (5, 7) then
x1 = 1
y1 = 3
x2 = 5
y2 = 7
Then put them into your distance formula.

yeah if im not mistaken the formula of the distance is (x2-x1)^2+(y2-y1)^2 right so all you have to do is replace the variables with the given numbers then solve. im sure you know which is the x and the y right?

the distance formula is
sqrt[(x1 - x2)^2 + (y1 - y2)^2]
hope this helps

E=x1 F=y1 K=x2 l =y2
x1-x2=-1
y1-y2=-1
divide them and it equals one i think lol.
if it equals thats what is important
