Answer:
[tex]3p,3q,3r[/tex]
Step-by-step explanation:
Dilation is not a rigid transformation, for it is not an isometry, hence a dilation produces similar and not congruent figures.
If we have to dilate a [tex]\bigtriangleup ABC[/tex] with scale factor of 3, with this centered at its origin,with its sides p, q and r. We'll have [tex]\bigtriangleup A'B'C'[/tex] having 3p,3q, 3r.
The slope in a Dilation is considered carefully when it is not dilated at its center. Well it is. And we're not dilating line segments, then it'll look like this (check below)
[tex]D_3(x,y) A'=3A, B'=3B, C'=3C\\[/tex]
So its line segments will be thrice the value of its original triangle as well.
