please help

2. Are the polygons similar? If they are, write a similarity statement and give the scale factor. The figures are not drawn to scale. (1 point) ABCD ~ KLMN; 7.2:1.8 ABCD ~ KLMN; 3:1.8 ABCD ~ NKLM; 3:5.4 The polygons are not similar.

@Loser66 can u help me

Directrix (directrix):

The two polygons are parallelograms because each has both pairs of opposite sides congruent.

OpenStudy (love10129151):

thanks

OpenStudy (love10129151):

so is it a @Directrix

OpenStudy (love10129151):

A

OpenStudy (love10129151):

or C

Directrix (directrix):

A does not look good because the the ratios of corresponding sides are not in proportion 7.2/5.4 = 3/1.8 = 7.2/5.4 = 3/5.4 is not true.

OpenStudy (love10129151):

so A @Directrix

Directrix (directrix):

No, A is not correct.

OpenStudy (love10129151):

D

OpenStudy (love10129151):

or no

Directrix (directrix):

@love10129151 You wrote the same thing twice for A and B Is this correct? A) ABCD ~ KLMN; B) ABCD ~ KLMN;

OpenStudy (love10129151):

ABCD ~ KLMN; 7.2:1.8 ABCD ~ KLMN; 3:1.8 ABCD ~ NKLM; 3:5.4 The polygons are not similar.

OpenStudy (love10129151):

yes it is correct

Directrix (directrix):

These side are not in proportion. So, I don't see how the polygons could be similar even though some of the angle pairs are.

Directrix (directrix):

@love10129151

OpenStudy (love10129151):

okay can u help me out with other one

Directrix (directrix):

What did you decide for the answer to this question?

Well, that is what I am thinking. You may want to get a second opinion.
