The Rhombus. A rhombus is a four-sided shape where all sides have equal length (marked "s"). Also opposite sides are parallel and opposite angles are equal. Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles.

Quadrilateral. A quadrilateral is a closed shape that is formed by joining four points among which any three points are non-collinear. In simple words, a quadrilateral is a polygon with 4 sides, 4 angles, and 4 vertices.
Parallelogram. Properties: 2 pairs of parallel lines. 2 acute and 2 obtuse angles. 2 pairs of sides that are equal length.

Examine the properties of the quadrilateral, including side lengths and angle measurement. Show step. Shape A A: 4 4 equal angles (right angles), each pair of opposite sides are equal in length, 2 2 pairs of parallel sides. Shape B B: One pair of equal angles (right angles), one pair of parallel sides.
Polygon Sides. The sides of a polygon define the name of the specific polygon because different polygons have different number of sides. For example, if a polygon has 3 sides, then it is called a triangle, whereas, if a polygon has 4 sides, it is a quadrilateral.
