Asequence of transformations maps abc onto a"b"c". the type of transformation that maps abc onto a'b'c' is a
when a'b'c' is reflected across the line x = -2 to form a"b"c", vertex
of a"b"c" will have the same coordinates as b.

just needed some points but try socratic

google dat sis

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
