Geometry Lessons 6-2/6-3 WS In #1-4, use the diagram of Name_______________________________ ABCD to find each value. 1. mA 2. mD 3. x 4. AB 5. Using the diagram at the right, your classmate says that QV 10 . Explain why that statement may not be correct. Write and solve equations to find the values of x and y in PQRS . 6. PT 2 x, TR y 4, QT x 2, TS y 7. PT y, TR x 3, QT 2 y, TS 3x 1 Find the value(s) of the variable(s) in each parallelogram. 8. 9. 10. The perimeter of ABCD is 92 cm. AD is 7 cm more than twice AB. Write and solve an equation to find the lengths of all four sides of ABCD . HINT: DRAW A PICTURE! In the figure, PQ = QR = RS. Find each length. 11. ZU 12. TU 13. XY 14. WV For what values of x and y must ABCD be a parallelogram? 15. 16. 17. 18. 19. 20. Can you prove that the quadrilateral is a parallelogram based on the given information? Explain. 21. 22. 23.
