Question 3

 

Pentagon \(ABCDE\) can be moved on top of pentagon \(A'B'C'D'E'\) by a reflection in the line labelled f.
The coordinates of A are (1, 7).

a	The perpendicular distance from A to line f is .
b	The perpendicular distance from A′ to line f is .
c	The x-coordinate of A′ is .

Pentagon \(ABCDE\) is congruent to pentagon \(A'B'C'D'E'\).
