Use the diagram to decide whether the statement is true or false. 5. Points A, R, and B are collinear. 6. BW and AT are lines. 7. RB and RT are opposite rays. 8. Plane D could also be named plane ART. E Find the perimeter and area of the polygon with the given vertices. 9. P(-3, 4), Q(1, 4), R(3, -2), S(-1, -2) W 10. J(-1,3), K(5, 3), L(2,-2) 11. The coordinate 6 has a weight of 2, the coordinate 9 has a weight of 2, and the coordinate 15 has a weight of 1. Find the weighted average. 12. BX bisects LABC to form two congruent acute angles. What type of angle can ZABC be? Acute angle. B 13. Given ZRST, U is in the interior of the angle, mZTSU is 6° less than 5 times m/RSU, and m/RST = 48°. Write and solve a system of equations to find m/RSU and mZTSU. MLTSU = 390 MLRSÙ=9² 14. In the diagram at the right, identify all supplementary and complementary angles. Explain.
