Take the main triangle, and the 2 smaller triangles. With a series of rotations/flips you can make any of the 3 triangles similar
Gucchi:
A and B make sense
darkknight:
ill be back in 5 min hol up
Gucchi:
Also C
jhonyy9:
we dont know nothing about AD
is perpendicular on BC or anything ?

it is perpendicular on BC
jhonyy9:
so than please mark it on this image bc. so how you posted it is very bad understand it
Gucchi:
mark which answer?
Gucchi:
so am i right with choice A, B, and C?
Gucchi:
@jhonyy9 are you still here?

how every 3 ?
jhonyy9:
check please the relation between sides in case of the great triangle and one from these two smalls
Gucchi:
i am so confused what is the answer
jhonyy9:
look on the great triangle and triangle ADC
great triangle and triangle ADB
ABC is similar with ?
Gucchi:
A

AD is aproximatly equale side BD in case of triangle ABD
what mean this ?
jhonyy9:
in case of the great triangle how you see the proportionality of these two sides ?
and how you see this proportionality ib case of triangle ADC ?

try get what triangle is similar with great triangle using the proportionality of corresponding sides

@563blackghost
Gucchi:
@jhonyy9 are you here?
jhonyy9:
ok i will try make you understanding more easy
look please on this image posted by you attached to this math problem
there is great triangle ABC with right angle A
and triangle ADB with right angle D
and triangle ADC with right angle D
in case of great triangle there is hypothenuse BC what correspond in triangle ADB to side AB and in triangle ADC to side AC
little side of triangle ABC is AC what correspond in triangle ADC to little side DC
but in triangle ADC the side AD is aproximatly equal side BD
so from these what result ?
the great triangle ABC is similar with what little triangle ?
hope you understand it now the way how you need think it to solve this exercise
jhonyy9:
when you check these statements you need check how are these written bc. hope you know that for example
when you write ABC similar CBD
from this result angle A equal angle C ,angle B equal angle B and angle C equal angle D
or in case of triangle ABC with right angle A so need correspond a right angle of D from smaller triangles
this is very very important
jhonyy9:
@vocaloid please do you can explain it more easy understandably ? tysm

okay i think understand.. can we do process of elimination?
Gucchi:
starting from choice A
Gucchi:
@jhonyy9 Choice A is correct, and choice B is incorrect
Gucchi:
choice C and Choice D seem correct
Gucchi:
Choice E is incorrect

Join the QuestionCove community and study together with friends!
well in that case it would just be choice A right?
jhonyy9:
choice A
look on the angles
how is written
ABD similar CBA
looking on the angles seem true but the proportionality of corresponding sides not is true bc. in case of triangle ABD these two sides seem aproximatly equales when in case of great triangle AB is so longest than AC
yes ? hope you see it

oh my god i did not realize that
Gucchi:
i mean how about choice C?
Gucchi:
wait @jhonyy9 i understand it now IM SO DUMB
jhonyy9:
in case of choice C the corresponding angles not are equal
<B with <D for example
Gucchi:
the answer is E

it would be DC ~ AD no?
Gucchi:
or AD ~ DC
Gucchi:
or am i wrong ?
jhonyy9:
past some 20 minutes you get the right answer but till i write to you that is correct you corrected it in wrong

here AD is similar by it self AD not with DC
Gucchi:
is it DC ~ AC?
jhonyy9:
and BD not is similar DC like side
@gucchi wrote:
is it DC ~ AC?
in choice E where you see DC similar AC ? not possible
jhonyy9:
E . DAB sim DCA
DC sim here AC
how ?
jhonyy9:
check please choice D in this way
hope so much that will help you understanding so easy

checked both and it doesnt work out, the remaining answer is choice B
Gucchi:
choice B is the right answer

I would say you would be right from looking at what Jhonny9 said and dark said. Then you went through and you made sure you were right by making sure the other options were not correct. So I think you are right.

thank you for atleast answering, jhonyy said it was either between B, D, and E, so i looked at each of them and B made most sense to me
Timmyspu:
Then I would go with b because you did the process of elimination

alright yeah, ill go with B thanks again
