Question 223861: I really dont get how to do proofs and such. We just started on them in Geometry but our teacher completely lost me. The homework seems like it is written in a foreign language to me.
The problem is:
Suppose point T is the midpoint of RS and point W is the midpoint of RT. If XY = (supposed to be about equal to) RT and TS has a length of z, write the length of the segment in terms of z for RT.

At least you're trying. That's the most important thing.

With a problem like this, your only hope of getting it is to draw pictures. PLEASE IGNORE ALL NUMBERS.
"Suppose point T is the midpoint of RS"

" . . . and point W is the midpoint of RT"

"If XY is equivalent to RT "

"and TS has a length of z"

"write the length of the segment in terms of z for RT."

The numbers make it harder to see, but I hope you can tell that XY is equivalent to TS. So, in terms of z, XY equals . It seems complicated, because of the way it's written, but it's not complicated. If they want some written proof, I suppose you could say that since T is the midpoint, then RT is equivalent to TS. And XY is equivalent to RT (given). Therefore, XY must be equivalent to TS.
