Chapter 2 Standardized Test PracticePages 122–1231.D;249,0.143,2.646,492.C; 2(7)23511, so (7, 11) is on the line.2(4)2355, so (4, 5) is on the line.2(22)23527, so (22,210) is not on the line.2(25)2313, so (25,213) is on the line.3.A; a protractor is used to measure angles, notlengths. A calculator is not a measuring tool. Acentimeter ruler is more accurate than ayardstick because its unit of measurement(centimeters) is smaller.4.B;DwEw>EwFwso DE5EF.8x235¬3x178x5¬3x1105x5¬10x5¬25.A;/ACF1/DCF5/ACDby the Angle AdditionPostulate. So m/ACF1m/DCF590 since/ACDis a right angle. Then /ACFand /DCFare complementary angles.6.C; inductive reasoning uses specific examples tomake a conjecture.7.A8.A; divide both sides by 3.9.The shortest distance is the length of thehypotenuse of the right triangle whose legs havelengths 120 yd and 53}13}yd. Use the PythagoreanTheorem to find the length of the hypotenuse.
