Are the triangles similar? If they are, identify the similarity ratio. A) Yes; the similarity ratio is 3:4. B) Yes; the similarity ratio is 2:3. C) Yes; the similarity ratio is 1:2. D) No; the triangles are not similar.
A, because if you match the left triangle's sides to the right triangle's sides and simplify the fractions the ratio is 3/4. 6/8= 3/4, 9/12=3/4. and 12/16=3/4
