square abcd has sides of length 3cm.

the points m and n lie on ad and ab so that cm and cn split the square into three pieces of the same area.

what is the length of dm?

Ineed asap. 35 points. in order for two polygons to be similar, two conditions must be met. first, all pairs of corresponding sides must be in proportion. second, all corresponding angles must be congruent. prove that angle congruence is not enough, by itself, to establish that two polygons are similar. do this by describing or drawing two polygons that are not similar but whose corresponding angles are all congruent.
