Help please! this is critical i need help so bad :( Which sequence of transformations creates a similar, but not congruent, triangle?

a. Rotation and translation
b. Reflection and rotation
c. Dilation and rotation
d. Translation and reflection

I believe that it is A

Step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
