The sides of two triangles are 6, 9, 12 inches and 2.5, 3.75, and 5 inches respectively. are the triangles similar ? explain your reasoning.

Since, the sides are proportional. Therefore, the two triangles are similar.

Step-by-step explanation:

Since:

and

also,

i.e., The sides are proportional.

Therefore, the two triangles are similar.

step-by-step :

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
