identify the midsegment. Then write an equation to show that its length is half the length of its parallel segment. The segment with length is the midsegment. 19. Midsegments of Triangles The four triangles formed by the midsegments of a triangle are congruent. The SAS or SSS postulates can be used in each case Page 5/10 In addition to using congruent corresponding angles to show that two triangles are similar, you can use proportional corresponding side lengths. Using the SSS Similarity Theorem Is either DEF or GHJ similar to ABC? AC B 16 8 12 DF E 12 6 9 JG H 16 10 8 SOLUTION Compare ABC and DEF by fi nding ratios of corresponding side lengths. Note: we can also use the Law of Sines to show that the other two angles are equal. SSS. SSS stands for "side, side, side" and means that we have two triangles with all three pairs of corresponding sides in the same ratio.
