quadrilateral PQRS is rotates 90 clockwise about the origin to form quadrilateral P’Q’R’S. what is the y-coordinate of point P

Which one ? is the answer and how to find this answer

Which of the following graphs could represent a quartic function?

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.
