A figure has reflectional symmetry across line a. Line a passes through the figure. Which statement is NOT true about the figure?
CLEAR CHECK
If you fold the figure along line a, the part of the figure on one side of the line will match up exactly with the part of the figure on the other side of the line.
If you place a mirror at line a, the uncovered half and its reflection form a figure with the same size and shape as the original.
Line a must divide the figure into two equal, yet mirrored, images.
The figure must have reflectional symmetry across the line perpendicular to line a that goes through the middle of the figure.
