List of Geometric Shapes – Quadrilaterals

List of Geometric Shapes – Quadrilaterals in Mathematics for students to learn. A quadrilateral is a polygon with four sides. A quadrilateral is sometimes referred to as a quadrilateral or a quadrilateral. There are quite a few members of the quadrilateral family.

There are also some members that are subset of other family members! See below if this confuses you!

Squares have 4 equal sides and 4 right angles.

They have 4 lines of symmetry. All squares belong to the rectangle family. All squares belong to the rhombus family. All squares are also parallelograms.

Rectangles have 4 sides and 4 right angles.

They all have 2 lines of symmetry (4 lines if they are also a square!) All rectangles belong to the parallelogram family.

Rhombuses (rhombii) have 4 equal sides.

Both pairs of opposite sides are parallel. They all have 2 lines of symmetry (4 lines if they are a square!). All rhombuses belong to the parallelogram family.

Parallelograms have 2 pairs of parallel sides.

Some parallelograms have lines of symmetry (depending on whether they are also squares, rectangles or rhombuses), but most do not.

Trapezoids US (Trapeziums UK) have one pair of parallel sides.

Some trapezoids have a line of symmetry. Please note the differences between the definitions for US and UK.

Kites have 2 pairs of equal sides which are adjacent to each other.

Convex and Concave Polygons – geometric shapes for kids

Polygons can be concave or convex in their shape.

Convex shapes have all angles less than 180°. Concave shapes have at least one reflex angle greater than 180°

Triangles are always convex.
