Proving triangle similarity
given: nm / xz
prove: axyz - anym
we know that side nm is
to side xz. if
we consider side ny the transversal for these parallel
lines, we create angle pairs. using the
, we can state that
zyxz is congruent to zynm. we know that angle
xyz is congruent to angle h y by the reflexive
property. therefore, triangle xyz is similar to triangle
nym by the similarity theorem.
