Consider the two triangles. Triangles A B C and H G I are shown. Angles A C B and H I G are right angles. The length of side A C is 15 and the length of side C B is 20. The length of side H I is 12 and the length of I G is 9. To prove that the triangles are similar by the SAS similarity theorem, it needs to be shown that...
AngleC congruent AngleC
AngleC congruent AngleG
AC/GI = HI/BC
AC/GI = BC/HI
