Here are two steps from the derivation of the quadratic formula. -- What took place between the first step and the second step? A. Factoring a perfect square trinomial

C. Completing the square

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.
