Answer:
16 - C (If a = bc, then a/b = c)
Explanation: Converse formula is basically the opposite so (If a/b = c, then a = bc) will switch around and turn into (If a = bc, then a/b = c)

17 - D (A perpendicular to AB through point G not on AB)
Explanation: The constructions is perpendicular to Line segment AB at point G

18 - B (12)
Explanation: WL and PL multiply together and KL and ZL multiply together and equal each other(It's a formula). So 5(x) = 2(3x-2)
5x = 6x-4 - distribution property
+4-5x +4-5x - Cancels out
4 = 6x-5x
4 = x
KL= 2
ZL = 3(4)-2 = 10
KL+ZL = 10+2 = 12
