Complete the coordinate proof for the quadrilateral determined by the points A(5, 7), B(7, 2), C(2, 0), D(0, 5). Prove that ABCD is a parallelogram. Slope of AB = (2-7)/(7-5) = Slope of BC = (0-2)/(2-7) = Slope of CD = (5-0)/(0-2) = Slope of AD = (7-5)/(5-0) = The slopes of opposite sides (select) equal. This means that opposite sides are (select), so ABCD (select) a parallelogram.

II. Complete each statement, using Parallelogram DCBA 4. If AD = 20, then BC = 5. If AB = 13, then DC = 6. If DB = 22, then DE = 7. If AE = 18, then AC = 8. If m∠ADC = 115°, then m∠ABC = 9. If m∠DAB = 75°, m∠ADC = III. Find the missing measurements of Parallelogram ADCB. 10. CD = 11. DA = 12. AC = 13. DB = 14. CE = 15. DE = 16. m∠ABC = 17. m∠BCD = 18. m∠ADC = 19. m∠BAD =
