Question 6

What additional information is needed to prove that the triangles are similar?

Revolt · Accepted Answer

✔ MN = 6 and XZ = 17.5; To prove △XYZ ~ △MNO using SSS, you need to know that .: MN = 6 and XZ = 17.5; Now that you know the length of XZ, you need to know that angle O is congruent to to prove △XYZ ~ △MNO using SAS.: angle Z
