Question

If AB=6and AC=8, which statement will justify similarity by SAS?

Answer 1

The answer to this problem is choice 4 because
$ab = 6 \: \: and \: \: ac = 8$
so we need to find the answer choice such that we can set up a proportion of sides that are equal
$\frac{ab}{de} = \frac{ac}{df}$
plugging in choice we find choice 4 is correct because
$\frac{15}{6} = \frac{20}{8}$
simplify and get
$2.5 = 2.5$
this would mean the sides are similar of both triangles. now we can consider the angle were given and justify that both triangles are similar under choice 4

Answer 2

1). is the correct answer.
