Triangle Similarity: SSS and SAS (Sec 7-3, 7-4, 7-5)
Question 9 • *CR CCSS Math 2 S2 [M2960OX]
What additional information is needed to prove that the triangles are similar? To prove △XYZ ~ △MNO using SSS, you need to know that . Now that you know the length of XZ, you need to know that angle O is congruent to to prove △XYZ ~ △MNO using SAS.
