50 POINTS EASY If a series of rigid transformations maps ∠F onto ∠C where ∠F is congruent to ∠C, then which of the following statements is true?

Statement 4 is true

Step-by-step explanation:

If the triangles are similar

F maps to C  and the right angles are D and A

DEF is similar to ABC

This eliminates the first two statements

Then we know  corresponding sides of similar triangles are proportional.

sdfghjkl; vbnm,

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.
