2; Selection 1: 2; Selection 2: 2; Selection 3: 2; Selection 4: SSS similarity

Question 8

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.

Revolt · Accepted Answer

MN = 6 and XZ = 17.5; Selection 1: MN = 6 and XZ = 17.5; Selection 2: angle Z
