Help me out with this question (geometry)

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)

Which of the functions graphed below has a removable discontinuity?

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.
