Question

The transformation of ∆DEF is described in the table.

What are the coordinates of E' that will justify ∆DEF ~ ∆D'E'F'?
A. (5, 4)
B. (6, 4)
C. (9, 6)
D. (12, 10)

Answer 1

The coordinates of E' is (6, 4)

Explanation:

Enlargement by scale factor 2

F(7, 6) = F'(14, 12)

= F' (2×7, 2×6)

E(3, 2) = E' (2×3, 2×2)

= E' (6, 4)
