For the triangles to be similar by the SSS similarity
theorem, what must be the value of y?

y = 20

Step-by-step explanation:

We have,

To be similar by

PR/AC = CB/RQ = AB/PQ

or, 28/14 = y/10 = y/10

or, 2 = y/10 = y/10

Taking 1st and 2nd ratio,

or, y = 2*10 = 20

I think it can not be similar with sss similarity

answer: h

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
