A rotation may be clockwise or counter clockwise. In this example the center of rotation is outside the figure. Many people think of symmetry in connection with art or architecture. The geometric concept of symmetry can be used to create balance in a design or building. Often this adds to the beauty of the design or building.
Line symmetry means that the figure can be folded along a line and the two halves match exactly.
Examples of familiar figures that have line symmetry are squares, rectangles, circles and hearts. A figure with point symmetry can be turned about a center point and in less than a whole turn the image looks like the original figure. Figure B demonstrates point symmetry. The point is in the center of the design. Figures may have point symmetry, line symmetry or both line and point symmetry.
