Which theorem or postulate proves that abc and def are similar?

select from the drop-down menu to correctly complete the statement.

the two triangles are similar by the

a. sss similarity theorem
b. sas similarity theorem
c. aa similarity postulate

The SSS stands for "side side side", so saying "SSS similarity" means the three corresponding sides are in the same proportion as each other.

Divide each side of DEF by its corresponding side of ABC

DE/AB = 18/3 = 6

EF/BC = 42/7 = 6

FD/CA = 36/6 = 6

We get 6 each time we divide, so the scale factor is 6. Each side of DEF is 6 times longer compared to its corresponding counterpart back in ABC.

Side note: the area of triangle DEF is 36 times larger since 6^2 = 36.

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
