This figure has reflectional symmetry across line a. Which statement is true about the figure?
An arrow folded in half on line a.
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 the edge of a mirror at line a, the uncovered half and its reflection will not form a figure with the same size and shape as the original.
Line a divides the figure into two unequal images.
The figure has reflectional symmetry across the line perpendicular to line a through the middle of the figure.
