Michael is thinking about how old professional tennis players are. He is considering investigating the following two questions.
Question A: How old is the oldest current professional tennis player?
Question B: How old are professional tennis players?
Which of these two questions is a statistical question and why?

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
