Question

Triangle ABC has vertices A(1,4), B(−2,4) , and C(−1,−1) . A dilation with a scale factor of 0.25 and center at the origin is applied to the triangle. What are the coordinates of B' in the dilated image? Enter your answer in the boxes.

Answer 1

-0.5 , 1

Explanation:

The scale factor is 0.25 and since we are trying to find coordinates to B prime, we look at B original because they are congruent. B has coordinates -2 , 4 so, we multiply -2 and 4 by the scale factor.

-2 * 0.25 = -0.5. 4 * 0.25 = 1

The (new) coordinates for B prime is -0.5 , 1.

Answer 2

So multiply to get answer.

B' is (-2*.25, 4*.25), or (-0.5, 1)

Answer: (-0.5, 1)
