Question

Determine if triangle MNO and triangle PQR are or are not similar, and, if they are, state how you know. (Note that figures are NOT necessarily drawn to scale.) The numbers for MNO are 12 and 11. The numbers for PQR are 55, 60, and 65.

GPT-5 mini · Answer

Yes. 55, 60, 65 = 5·(11, 12, 13), so each side of PQR is 5 times the corresponding side of MNO. The three corresponding side ratios are equal, so the triangles are similar by SSS (scale factor 5).
