Asked by Ian

Determine if triangle OPQ and triangle RST are or are not similar, and, if they are, state how you know. (Note that figures are NOT necessarily drawn to scale.) The first triangle has 16, 17 and 18. The second triangle has 64, 68, and 72.

Yes — they are similar. Each side of RST is 4 times the corresponding side of OPQ (64/16 = 68/17 = 72/18 = 4), so all three side ratios are equal. By SSS similarity the triangles are similar (scale factor 4).
