In a geometry class, you have been asked to measure the three interior angles of each triangle in Figure 1.4. You discover that triangles I, II, and IV have two angles (as marked) that have equal measures. What may you conclude? CONCLUSION The triangles that have two sides of equal length also have two angles of equal measure. 3 cm 1 cm 5 in. 3 in. 3 cm II 4 cm 4 cm 4 in. 5 in. 6 ft 5 in. 3 ft 2 cm IV V 7 in. 7 ft Figure 1.4
