Q:

# Is a square a rhombus?

A:

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.

Without a specific exclusion, a square qualifies not just as a rhombus but also as a specific type of rectangle, since it is a four-sided figure with four congruent, 90-degree angles. In fact, squares, rectangles and rhombuses can all be considered specific types of parallelograms. However, even if all squares are rhombuses, not all rhombuses are squares.

To figure out the square footage of an area, one must first measure the sides of the area or the diameter of the area if the area is round. Then, depending on the shape of the area, the appropriate formula must be applied to determine the square footage.

Even though both rectangles and rhombuses are quadrilaterals and parallelograms, they are different figures. Rectangles have four 90-degree angles and parallel opposite sides of equal length. Rhombuses have four equal-length sides, parallel opposite sides and equal opposing angles. Rhombuses are normally referred to as diamonds.

The angles that lie on the exterior of the intersection created on opposite sides of a paired set of intersecting lines are alternate exterior angles. If the two intersecting lines are parallel, the alternate exterior angles are congruent.
