Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

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.

Which of these lines passes through the point (1,-1) and has a slope of -3?
