Triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation: two triangles are drawn on a grid. first triangle has vertices j 6 and 12, k 9 and 6, l 12 and 9. image triangle has vertices j prime 2 and 4, k prime 3 and 2, l prime 4 and 3. which scale factor was used to create triangle j'k'l'? 1 by 3

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
