Quadrilaterals. Quadrilateral just means "four sides". ( quad means four, lateral means side). A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
- Square. A square has four sides of equal length. It has four right angles (90°). The opposite sides are parallel. The each other at right angles.
- Rectangle. A rectangle has two pairs of equal sides. It has four right angles (90°). The opposite sides are parallel. The diagonals bisect each other.
- Parallelogram. A parallelogram has two pairs of equal sides. It has two pairs of equal angles. The opposite sides are parallel. The diagonals bisect each other.
- Rhombus. A rhombus has four sides of equal lengths. It has two pairs of equal angles. The opposite sides are parallel. The diagonals bisect each other at right angles.
Angles in a quadrilateral are the four angles at each vertex within the shape. They add up to 360. Learn properties, types, formulas, and more.
