In geometry, a line of symmetry is a line that divides a shape into two halves that match exactly, as if reflected in a mirror. Line symmetry is sometimes called reflective symmetry because each point on one side of the ... More »

A kite, which is a quadrilateral with two different pairs of adjacent sides that are equal in length, has only one line of symmetry. A line of symmetry for any polygon can be found by reflecting the polygon over a line s... More »

Some shapes that have no lines of symmetry include the scalene triangle and trapezium. A trapezium is a four-sided flat shape with straight sides, none of which are parallel. Outside of the United States, the trapezium i... More »

An axis of symmetry is a line that divides a shape into two halves. When the shape is folded over this line, the two sides are congruent. For quadratic functions, the axis of symmetry is a vertical line given by a specif... More »

If a shape or image can be rotated less than 360 degrees and still retain the same appearance, this shape has rotational symmetry. For example, a five-pointed star can be turned to allow a different point to face upward ... More »

Mathematics plays a key role in determining proportion, symmetry, shape and patterns, and is therefore an integral part of visual art. Mathematics can be used to explain and describe works of art and architecture. More »
