Given: S,T, and U are Collinear and ST = TÚ
Conjecture: T is the midpoint of line SU
Is this true or false?



Answer :

it's true
collinear means they are on the same line so ST=SU
so if ST= 50 then SU=50 making T the midpoint of line that is 100
s----------------t-----------------u
         50                      50
