Q:

How is a rhombus similar to a square?

A:

A rhombus is similar to a square in two ways: both have two pairs of parallel sides and both have four equal sides. A rhombus is different from a square because it does not have four right angles. All squares are also rhombuses.

A rhombus is one of several types of four-sided shapes known as quadrilaterals. Other quadrilaterals are rectangles, parallelograms, kites and trapezoids. In addition to the square, a rhombus is similar to a parallelogram because both shapes have two sets of parallel sides. While all rhombuses are parallelograms, a parallelogram is not a rhombus because it does not have four equal sides. The area of a rhombus can be calculated by multiplying its height by its side length. The perimeter is calculated by multiplying the length of a side by four.

A rhombus is an equilateral parallelogram, which is a two-dimensional, four-sided figure in which opposite sides are parallel and all sides have equal length. A square fits this definition. However, it is usually considered a special case, and some definitions of a rhombus specify that squares are not included.

A square is always a rhombus; it is a special kind of rhombus where all four corners are right angles. A rhombus is a two-dimensional geometric shape with four equal-length, straight sides.
