How many of these figures have at least one vertex?

Ade and abc are similar. which best explains why the slope of the line between points a and d is the same as the slope between points a and b?

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why? a. point c could be the interior of aob but it is not the only case b. point c is the interior of aob c. point c is not the interior of aob d. the given is not possible for the plane geometry answer
