Concave and Convex Quadrilaterals
Based on the value of internal angles, quadrilaterals or any other polygon can be classified into concave and convex.
Concave Quadrilaterals
Those quadrilaterals which have at least one of the interior angles greater than 180° are called concave quadrilaterals. We can also define concave quadrilaterals as those quadrilaterals for which any one of its diagonals lies outside the area bounded by the sides of the quadrilateral.
Convex Quadrilaterals
Those quadrilaterals in which all the interior angles are less than 180° are called convex quadrilaterals. We can also define convex quadrilaterals as those quadrilaterals for which none of its diagonals lies outside the area bounded by the sides of the quadrilateral.
Types of Quadrilaterals and Their Properties
A quadrilateral is a polygon with four sides, four vertices, and four angles. There are several types of quadrilaterals, each with its own properties and characteristics. All different types of quadrilaterals have very distinct shapes and properties which help us identify these quadrilaterals.
As we know, quadrilaterals are polygons with four sides, four interior angles, and four vertices. With its unique sets of properties and characteristics, there can be various quadrilaterals such as square, rectangle, parallelogram, rhombus, trapezium, and kite.
Understanding these different types of quadrilaterals helps us understand the fundamentals of geometry and also helps us deal with further advanced topics in mathematics such as trigonometry and calculus.
In this article, we will explore the different types of quadrilaterals, Properties of Different Types of Quadrilaterals, and how they differ from one another.
