Question 5

Question 5

Revolt · Accepted Answer

To prove two triangles are similar using the SAS similarity theorem, you must show that two pairs of corresponding sides are proportional and that the included angles (the angles between those sides) are congruent.

Question 6

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

B: MN = 6 and XZ = 17.5
