Look at the figure shown below: cb is a segment on which a perpendicular bisector ad is drawn. d is the midpoint of cb. which step should be used to prove that point a is equidistant from points c and b? triangle abd is congruent to triangle acd. prove that segment ad is perpendicular to bc. triangle abd is similar to triangle acd. prove that segment ad is equal to segment bc.

ΔABD ≅ ΔACD    CPCTC follows this step to complete the proof

AD ⊥ BC                already given information

ΔABD ~ ΔACD      this proves ratio, not congruency

AD = BC                this might be a false statement, we only know that CD = DB

A) ΔABD ≅ ΔACD

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
