Triangle J’K’L’ shown on the grid below is a dilation of triangle JKL using the origin as the center of dilation: Which scale factor was used to create triangle J’K’L?

A.) 4
B.) 1/4
C.) 2
D.) 1/2

Option (D)

Step-by-step explanation:

Coordinates of J, K and L are,

J(8, 12), K(4, 8) and L(12, 6)

Distance between two points and is given by the formula,

d =

Length of JK = =

                     =

Coordinates of the image triangle,

J'(4, 6), K'(2, 4) and L'(6, 3)

Length of J'K' = =

Scale factor =

                    =

                    =

Therefore, Option (D) will be the correct option.

question:

could we have options?
