In the diagram, polygon abcd is flipped over a line of reflection to make a polygon with vertices at a′, b′, c′, and d′. points a', b', and d' are shown, but the line of reflection and point c′ are not. what are the coordinates of c'′ ?

a. (6, 2)

b. (5, 2)

c. (7, 2)

d.(12, 2)

if point A( 2,2) is reflected across the line Y then the new position A' is (-2,2) and the distance AY = distance A'Y if A is reflected across line R it is now at point B and the distance AR = distance BR lets say the point A(2,2) was perpendicular to the line R at the point (1, 4) then when reflected the point A now at location B will have coordinateswhen flipped over a line of reflection the lengths are still the same the point to the line of reflection is the same length as the line of reflection to the reflected position the distance from the original point to the reflected point is twice the distance from the original point to the line of reflection cannot see your polygon. here is an example
