I got SSS, because \[\Delta bcd ~ \Delta jkl\] its sposed to say is similar but you get my point @jim_thompson5910

jimthompson5910 (jim_thompson5910):

let me check

jimthompson5910 (jim_thompson5910):

BCD ~ JKL is the claim Let's use the SSS similarity theorem to verify BC/JK = CD/KL = BD/JL 54/9 = 72/12 = 60/10 6 = 6 = 6 so the claim has been confirmed using the SSS similarity theorem. Nice work

OpenStudy (bookworm14):

oh yeahhh! :D for this next one, i got SAS , but i know it is similar i checked, and i thought it would be SAS because the sides a proportionate and they have a congruent angle, would that be right ?

jimthompson5910 (jim_thompson5910):

yes it is the SAS similarity theorem what would be the proper order?

OpenStudy (bookworm14):

FGH ~ SRQ ?

jimthompson5910 (jim_thompson5910):

correct

OpenStudy (bookworm14):

for this one I got SSS, all fractions = 2.4 so sides are proportionate, but not angles that im aware of

OpenStudy (bookworm14):

CDE ~ CML I think

jimthompson5910 (jim_thompson5910):

CDE ~ CML CD/CM = 96/40 = 2.4 DE/ML = 168/70 = 2.4 CE/CL = 156/65 = 2.4 so these triangles are similar by the SSS similarity theorem this means that the corresponding angles are definitely congruent, ie, C = C D = M E = L

OpenStudy (bookworm14):

i thought that, but didnt wanna confuse myself just in case....So does that mean would it still be SSS or no?

OpenStudy (bookworm14):

0h wait nvrmnd i see where you said it was

OpenStudy (bookworm14):

Last one!!! I got that this one was not similar lol

jimthompson5910 (jim_thompson5910):

agreed, none of the angles are congruent. We need 2 pairs of congruent angles to use AA similarity theorem

sorry i am amultitasking, thank you so much!
