“ If parallel lines cut off congruent segments on one transversal, then they cut off
congruent segment on any transversal.” Graph given below shows similar triangles
used to depict fuel economy standards for automobiles. Above thermo can be used to
divide a given segment into any number of segment into any number of segment into
any number of congruent parts.
