Which two triangles are similar?

OpenStudy (anonymous):

@abhilash11

OpenStudy (anonymous):

Yesh a min :D

OpenStudy (anonymous):

The answer could be B

OpenStudy (anonymous):

Does anybody disagree

OpenStudy (sleepyjess):

The answer is not B

OpenStudy (anonymous):

See, instead of probably not checking with width, can we instead check slope of lines? Yeah, so here, the lines with same slopes shall be similar :-)

OpenStudy (sleepyjess):

For triangles too be similar, the ratios of all 3 sides must be the same. For example, if 2 triangles have the ratio 1:2 on all 3 sides, then they are similar.

OpenStudy (anonymous):

so know wht would be they answer if it is nit b

OpenStudy (anonymous):

Yeah. :-D @sleepyjess see the common line to the three triangles? It has got 3 point right? Hence two lines? Their ratio is same, ie 2/3 So we're left with checking thrree triangles, B A and C :D

OpenStudy (anonymous):

Answer is C!

OpenStudy (anonymous):

Omg!! how could I overlook! O.o okay okay so here's the solution :-D

OpenStudy (anonymous):

does everybody agree

OpenStudy (anonymous):

See, first we need to check the slopes. They need to be equal to atleast one side of each triangle

OpenStudy (anonymous):

Check triangles C and D. they are simliar cause of two reasons

OpenStudy (anonymous):

1. The respective lines are parallel to each other. Hence slopes are equal.

OpenStudy (anonymous):

2. cause both are right angle triangles!! :-P xD

OpenStudy (anonymous):

Okay I agree with abhilash11

OpenStudy (anonymous):

Yeah :-D :-) We all probably overlooked :-)

OpenStudy (anonymous):

answer is c, c and d

OpenStudy (sleepyjess):

@Hamood_65 Please do not just give an answer.

OpenStudy (anonymous):

no it can not be more than one answer

OpenStudy (anonymous):

@Hamood_65 it cannot be D bro

OpenStudy (anonymous):

See here why .

OpenStudy (sleepyjess):

He was saying C. C and D as that is how option C is shown.

OpenStudy (triciaal):

@Abhilash11 be more careful when reading

OpenStudy (anonymous):

Oh okay! :-)

OpenStudy (anonymous):

My bad. :-)

OpenStudy (anonymous):

Thanks @sleepyjess

OpenStudy (sleepyjess):

It's ok! We are only human and we all make mistakes.

OpenStudy (anonymous):

its ok

OpenStudy (anonymous):

:-)

OpenStudy (anonymous):

so its c

OpenStudy (anonymous):

Yupp

OpenStudy (anonymous):

yeah :)
