If so, state how you know they are similar and complete the similarity statement. (Last questions I need help with)

triangle BCD is similar to triangle KJL because of SSS similarity.

triangle FGH is not similar to triangle SRQ.

triangle CDE is not similar to triangle MLC.

triangle LMN is not similar to triangle FEG.

First one top left....we can check these ratios

9/54 = 10/60 = 12/72 = 1/6 Similar due to SSS proportionality

So ΔBCD is similar to ΔJKL

Top right

Check these ratios

60/156 = 65 /169

5/13 = 5/13 Similar due to SAS proportionality

So ΔFGH is similar to ΔSRQ

Bottom left

Check these ratios

40/96 = 65/156 = 70/168

5/12 = 5/12 = 5/12 Similar due to SSS proportionality

So ΔCDE is similar to ΔCML

Bottom right

Not similar - no angles match

Look at this

Angle B is opposite the longest side Angle J is opposite the longest side

Angle C is oppositie the mid-length side Angle K is opposite the mid-length side

Angle D is opposite the shortest sde Angle L is opposite the shortest side

So

ΔBCD is similar to ΔJKL
