Types of Quadrilateral
Based on their properties, quadrilaterals are divided into two major types:
- Convex quadrilaterals and
- Concave quadrilaterals.
These concave and convex quadrilaterals can be further classified into their subdivisions.
Concave Quadrilateral
Quadrilaterals that have one interior angle greater than 180° and one diagonal lies outside the quadrilateral are called concave quadrilaterals.
One of the examples of a concave quadrilateral is a Dart. It is a quadrilateral with bilateral symmetry like a kite, but with a reflex interior angle.
Here, in the image given below, one of the interior angles of the quadrilateral is 210°, which is greater than 180°. Therefore, the quadrilateral is a concave quadrilateral.
Convex Quadrilateral
Quadrilaterals that have all four interior angles less than 180° are called concave quadrilaterals.
There are various types of Convex Quadrilaterals, which are :
- Trapezium
- Kite
- Parallelogram
- Rectangle
- Rhombus
- Square
Quadrilateral – Definition, Properties, Types, Formulas, Examples
Quadrilateral: A quadrilateral is a two-dimensional figure characterized by having four sides, four vertices, and four angles. It can be broadly classified into two categories: concave and convex. Within the convex category, there are several specific types of quadrilaterals, including trapezoids, parallelograms, rectangles, rhombi, and squares.
The sum of the interior angles of a Quadrilateral is 360°. Let’s learn what is a quadrilateral, its shapes, types, properties, formulas, and examples in detail.
