The lengths of the new triangle after dilation are; J'K' = 3; K'L' = 5.25 and L'J' = 6
How to carry out dilation of triangles?
When it comes to dilation in transformations, it could mean enlarging or reducing the triangle by a scale factor.
Now, we are given the lengths of the original triangle as;
JK = 6 units
KL = 10.5 units
LJ = 12 units
Thus, the dilation by a scale factor of 1/2 indicates a reduction. Thus, the new lengths after dilation are;
J'K' = (1/2) * 6 = 3
K'L' = (1/2) * 10.5 = 5.25
L'J' = (1/2) * 12 = 6
