Asked by Ian
Determine if triangle PQR and triangle STU 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 PQR are 25, 19, and 19. The numbers for STU are 100, 76, and 76.

Yes — they are similar.
Each side of triangle STU is 4 times the corresponding side of triangle PQR: 25:100 = 19:76 = 1:4. Therefore the triangles are similar by SSS similarity (scale factor 4).
