No words here — just shapes, reflections and hidden figures. A mirror flips left-right, a water reflection flips top-bottom, and a bigger figure can hide several smaller ones inside it at once.
Find the repeating group, or watch how a shape rotates or grows from picture to picture.
A mirror on the side swaps left and right. Letters with a vertical line of symmetry look unchanged.
Unchanged in a mirror (vertical symmetry)
A H I M O T U V W X Y
Among digits, only 0, 1, 8 are unchanged.
A water reflection (like in a still lake) flips top and bottom instead of left and right.
Unchanged in a water image (horizontal symmetry)
B C D E H I K O X
Among digits, 0, 3, 8 are unchanged.
Notice: H, I, O and X appear on BOTH lists — they have a vertical AND a horizontal line of symmetry, so they look the same in a mirror image and a water image.
Count the smallest shapes first, then the ones made by joining two or more together, then the whole outline.
