Which pairs of triangles are similar? check all that
apply.
aabc - adef
adef - aghi
ο δghi - δabc
o aghi - ajkl
ajkl - aabc

JKL and ABC

DEF and GHI

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding angles is proportional and its corresponding angles are congruent

so

In this problem

1) triangles JKL and ABC are similar

because

substitute the given values

Simplify

 ---> is true

therefore

The ratio of the corresponding sides is proportional

That means----> The triangles are similar

2) triangles DEF and GHI are similar

because

substitute the given values

Simplify

 ---> is true

therefore

The ratio of the corresponding sides is proportional

That means----> The triangles are similar

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)

c is the correct answer
