In figure, the point C is the image of point A in line I and line segment BC intersects the Iine l at P.

(a) Is the image of P in line I the point P itself?
(b) Is PA = PC?
(c) Is PA + PB = PC + PB?
(d) Is P that point on line I from which the sum of the distances of points A and B is minimum?

(a)

Draw the images P', Q' and R' of the points P, Q and R, respectively in the line n. Join P 'Q' and Q' R' to form an angle P'Q'R'. Measure ㄥPOR and ㄥP'Q'R'. Are the two angles equal?
