Hello I really need help with my son's homework. Please help

Green Worksheet Starts Here 1. Prove that quadrilateral ABCD is a rhombus. B C - 5 0 A D - 5- Part A: Prove that ABCD is a rhombus. Step 1: Demonstrate that all four sides are congruent. Show your work either on Kami in the spaces or on a separate sheet of paper. Length of AB Length of BC Length of CD Length of AD Step 2: Explain why ABCD is a rhombus. ABCD is a rhombus because2. Prove that quadrilateral ABCD is a rectangle 10 C A - 5 O 5 10 B -5 Part A: Prove that ABCD is a Rectangle. Step 1: Find the slopes of a pair of consecutive sides Slope of AB Slope of BC Slope of CD Slope of AD Step 2: Explain why ABCD is a rectangle ABCD is a rectangle because Green Worksheet Starts Here1. Prove that quadrilateral ABCD is a rectangle. B(5,7) A(-5,3) C(7,2) -5 0 5 10 D(-3,-2) Part A: Prove ABCD is a parallelogram. Find the slopes of all four sides. Show your work either on Kami in the spaces or on a separate sheet of paper. Slope of AB: Slope of CD: Slope of AD: Slope of BC: Explain why quadrilateral ABCD is a parallelogram. Properties and Proving Checklist ABCD is a parallelogram because opposite sides are because their slopes are Part B. Prove ABCD is a rectangle: Explain why parallelogram ABCD is a rectangle. Properties and Proving Checklist ABCD is a rectangle because consecutive sides are because their slopes are2. Prove that parallelogram EFGH is a square (a square is a combination of a rectangle and rhombus) F(0,5)- E(-5,3) -5 G(2,0) H (-3,-2) Part A: Prove that EFGH is a rectangle. Find the slopes of all four sides. Show your work either on Kami in the spaces or on a separate sheet of paper. Slope of EF: Slope of FG: Slope of GH: Slope of EH: Explain why quadrilateral EFGH is a rectangle Properties and Proving Checklist EFGH is a rectangle because consecutive sides are because their slopes are Part B: Prove that EFGH is a rhombus. Find the distances of all four sides. Show your work either on Kami in the spaces or on a separate sheet of paper. Length of EF: Length of FG: Length of GH: Length of EH: Explain why quadrilateral EFGH is a rhombus Properties and Proving Checklist EFGH is a rhombus because all sides are because their lengths are Part C: Prove that EFGH is a square by demonstrating it is both a rectangle and a rhombus. Use your explanations in Part A and Part B
