Question

Triangle ABC, with coordinates A(2, 3), B(3, 5), C(7, 4), is dilated by a scale factor of 2. What are the coordinates of the dilated figure, triangle A′B′C′?

Answer 1

A' = (4, 6) B' = (6, 10) and C' = 14, 8).

Explanation:

Answer 2

Bellow in bold.

Explanation:

Multiply each coordinate by 2:

A(2, 3) ---> A' = (2*2, 3*2) = (4, 6)

In a similar way B' = (6, 10) and C' = 14, 8).
