Try to figure out the proportion of all the two pairs of polygons first.

8 and 10 for first 50 and 30 for 2nd 36 and 48 for 3rd 21 and 30 for the 4th

Do you know what is needed for two polygons to be similar?

no but i just need to get this done quick its been 10 minutes all ready. :(

please @madhu.mukherjee.946 help or @mathstudent55

i have already told you

ok so i'm thinking D

you go to check both the polygons and see if they are similar based on the the two conditiond

well the only ones that are really similar is D

Let's look at the first choice.
Is 6/7 = 2/3? No, not even close, so eliminate choice A.

ive been saying D -_-

its d

Choice B.
Is 15/9 = 35/21 ?
Let's reduce both fractions: 5/3 = 5/3 Yes, it works.
Choice B works.

Choice C.
Is 12/18 = 24/30 ?
Reducing, we get: 2/3 = 4/5. Not true. Choice C does not work.

okay

thanks

You're welcome.
