A symmetrical figure is one that has a point, line, or plane of symmetry. The figure looks the same whether you go in one direction from the point/line/plane of symmetry, or whether you go in the opposite direction.

Examples A circle is symmetrical about its center point, and about any line through the center point.

A square is symmetrical about its center point, and any line through opposite corners, and any line through the midpoints of opposite sides.

A rectangle is symmetrical about its center point, and any line through the midpoints of opposite sides.

In many fonts, the capital letters A, H, I, M, O, T, you, V, W, X are symmetrical about a vertical line through the center of the letter. The capital letters O and S are sometimes symmetrical about the center point of the letter.
