Answer 1

@hartnn @jim_thompson5910 Can one of you help?

Answer 2

you know the concept of similar triangles ?

Answer 3

infact, congruent triangles ?

Answer 4

Postulates or what?

Answer 5

when triangles re congruent, their sides are equal
know this ?

Answer 6

Yeah.

Answer 7

so can u prove those triangles congruent first ?

Answer 8

No you need the values of x and y to find the side lengths to identify concurrency.

Answer 9

do you know about AAS test for congruency ?
and one side is indeed given equal, if you look, by that small line mark

Answer 10

Oh. Yeah. So we know they're congurent.
