Question

Triangle ABC is similar to triangle PQR:

Answer 1

Which equation is correct?

Answer 2

which one do u think?

Answer 3

just remember:sides opposite to equal angles are proportional

Answer 4

I don't fully understand the answer choices or the question really.

Answer 5

ok let me explain

Answer 6

when you have similar triangles then their corresponding angles are equal
and
the ratios of their corresponding sides are also equal

Answer 7

to work easily with these 2 triangles
you'll need to rotate the second triangle slightly anti-clock wise, i'll draw u a pic

Answer 8

I didn't draw the angles so as not to clutter the picture, so far do u understand what was done? or u have questions?

Answer 9

You rotated the angles.

Answer 10

That's correct, I rotated the 2nd triangle so as to make the equal angles correspond to each other

the following angles are equal - this is for ur knowledge only...
A=P , B = Q , C = R

Answer 11

now the ratios bit, we can do it in ways, either start with the left triangle and then the right one or vice-versa
I'll show u both

1) a/p = c/r = b/q

or the other way around

2) p/a = r/c = q/b

given the above and what you understood so far, can you find the right answer?

Answer 12

Is it

Answer 13

Excellent!
