Question

Triangle RST is dilated by a scale factor of one quarter 1/4 to form triangle R'S'T'. Side TR measures 4. What is the measure of side T'R'?

Answer 1

Since the scale factor of the dilation is 1/4, the length of side T'R' will be 1/4 of the length of side TR.

Thus, T'R' = (1/4) * 4 = 1

Therefore, the measure of side T'R' is 1.
