to be is not same as to be
The of a triangle is a from a to the of the opposite side.
Given:
Triangles and proportional to proportional to
and median proportional to
to prove:
trianglesand are similar
~
proof:
prove that three sides of triangles are proportional
since is midpoint of , then
is proportional to and proportional to
since
and
we can conclude that is proportional to
two triangles and have three sides that are proportional
proportional to proportional to
and proportional to
therefore triangles and are , or
