Points A, B, and C are collinear. Point B is between A and C. Find the length indicated. 11) BC = 3x + 1, AB = 6, and AC = 4 + 4r.
Find BC.
12) AB=12, BC= 21 - 21, and AC=x+2.
Find AC
I
13) Find BC if AB= 2r- 2, BC= 2r-8,
and C= 10.
14) Find AC if AC=x+22, AB=5,
and BC= 2x + 27.

This is what i found “answer: a rigid transformation preserves both the side lengths and the angle measures of a polygon. step-by-step explanation: rigid transformations are the transformations which does not affect the size and the shape of figure .” i hope this you for what your looking for. can you plz mark me brainliest?
