Accurately draw each triangle described. Predict whether your triangle will be congruent to your classmates'. a. In ARST. RS = 4 cm, mZS = 45. and ST = 6 cm. b. In AUVW. mZ.U = 30. UV = 5 cm. and m L V = 100. c. In ADEF. mZ.D = 30. mLE = 68. and mLF = 82. d. In AXYZ, XY = 3 cm. YZ = 5 cm. and XZ = 6 cm. (Try for a reasonably accurate drawing. You may find it helpful to cut a thin strip of paper for each side, then form the triangle.)
