Mirror reflection preserves the number of sides and shape properties. A pentagon remains a pentagon with 5 sides.
Digits 0, 1, and 8 have vertical line symmetry and appear identical in a vertical mirror reflection.
Water image (horizontal reflection) reverses left-right orientation. A right-pointing arrow becomes left-pointing arrow.
The symbol ⊕ (circle with cross) has both vertical and horizontal line symmetry. Triangle has only vertical, diamond has both diagonals but the question refers to perpendicular axes, and arrow has neither.
Water image involves horizontal reflection, reversing the order of elements. '5 3 8 1' becomes '1 8 3 5' when reflected horizontally.
Water image involves horizontal mirror reflection. Vertical positions are inverted, so 3cm upward becomes 3cm downward.
Vertical mirror reflection (left-right reversal) moves the right angle from bottom-left to bottom-right.
Angles remain unchanged in mirror images. The 60-degree angle stays 60 degrees because angles are geometric properties preserved in reflection.
The letter 'A' has vertical axis symmetry, so it appears identical in both mirror and water images.
When 'b' is reflected horizontally in a mirror, it becomes 'd' as the bulge shifts from right to left.
