do a two column for the following...

Given: line segment RV; length of line segment RT= length of line segment SV.
Prove: length of line segment RS= length of line segment TV.

3 answers

what if S and T do not lie on RV?
r_____s________________t_______v
that is what the image looked like.
RS+ST+TV = RV
RT = RS+ST
SV = TV+ST

see what you can do with that.
