Which describes how triangle FGH could be transformed to triangle F prime G prime H prime in two steps?
Which identifies the transformation that occurred after the dilation?
a) a dilation by a scale factor of 3 and then a reflection across the x-axis
b) a dilation by a scale factor of 3 and then a 180 degrees rotation about the origin
c) a dilation by a scale factor of 4 and then a reflection across the x-axis
d) a dilation by a scale factor of 4 and then a 180 degrees rotation about the origin

a is the correct

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

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
