Question

The coordinates of ABC are (-3,4),(0,4),And (2,5). The coordinates of A’B’C’ are (-1.5,2),(0,2) And (1,2.5). How do you know that the transformation is a dilation.

Answer 1

The coordinates of triangle ABC have been multiplied by a scale factor of 0.5

Explanation:

By considering the given points, we can determine that the coordinates have been cut to half or each of the coordinate is divided into two. For instance:

(-3,4) is divided by 2 to give (-1.5,2)

(0,4) is divided by 2 to give (0,2)

and (2,5) is divided by 2 to give (1,2.5)

Therefore the later figure will be half in size in comparison to the first one.
