David drew pqr and stu so that p s, pr = 12, su = 3, pq = 20, and st = 5. are pqr and stu similar? if so, identify the similarity postulate or theorem that applies.

Step-by-step explanation:

In the figure attached there are two triangle PQR and STU have been given.

We have to prove both the triangle are similar.

If these two triangles will be similar if corresponding sides should have the same ratio.

4 = 4

Hence the given triangles are similar

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
