Identify the postulate or theorem that proves a∥b.

Given: ∠2≅∠7

The coordinates of a, b, and c in the diagram are a(p,4), b(6,1), and c(9,q). which equation correctly relates p and q? hint: since is perpendicular to , the slope of × the slope of = -1. a. p - q = 7 b. q - p = 7 c. -q - p = 7 d. p + q = 7

Which property was used to simplify the expression? 3c+9 +4c=3c+4c+9

Point a (7,3) is translated to a'(16,-9). which rule describes the translation?
