Quadrilateral: Learn about quadrilaterals

Learn about quadrilaterals, four-sided polygons with various shapes and properties. Find out the formulas for area and perimeter of different quadrilaterals and see solved examples. Introduction Quadrilateral is one of the type of polygons, which we already studied in the chapter Curve, Polygon and Types of Polygon. From this chapter, we can recall that a quadrilateral is a polygon which has four sides and four interior angles. In this chapter, we will learn in detail about the quadrilateral about its sides, diagonals. angles and its different types. Definition Quadrilateral is a plane closed figure formed by joining four line segments. It is a polygon with four sides ... A quadrilateral , in general, has sides of different lengths and angles of different measures. However, squares, rectangles, etc. are special types of quadrilaterals with some of their sides and angles being equal. This is the reason that the area of quadrilateral depends on which type of quadrilateral it is. In this article, we will discuss the special types of quadrilaterals and their basic properties.
