If it is a true / false question, then the answer is true. Assuming two line segments are congruent if and only if they have the same length, a line reflection preserves that length and a stretch/shrink does not [unless either scale factor is -1, 0, or 1, but "dilation" suggests | scale factor | is greater than one; or segment lengths are both zero but then they are points and not nondegenerate segments; or both].

3m+7=four.2m+five -7 or five on each side and isolate the variable via dividing via the coefficient you realize the relaxation I wish three.5r+two=2r+five -two or five on each side and do the equal isolate the variable and divide via the coefficient. If whatever is "congruent" that suggests they're the equal. so XS goes to be the equal reply at YT as for YS and XT. Hope this is helping
