If ABCD is a quadrilateral with AC as diagonal, then we can split the quadrilateral into two triangles ABC and ACD. In the case of orthogonal quadrilaterals ( such as square, kite, and rhombus), the formulas are minimized toĪrea of Quadrilateral Formula Coordinate Geometry Where a, and b are the length of the diagonals of a quadrilateral and is the angle between them. The formula to find the area of quadrilateral in trigonometric terms is given as: Hence, the formula to find the area of the quadrilateral is derived as:Īrea of General Quadrilateral Formula = 1/ 2 x diagonals length x ( sum of the height of two triangles ).Īrea of Quadrilateral Formulas in Trigonometry Terms Therefore, the area of quadrilateral PQRS isĪrea of ΔPSR + Area of ΔPQR = 1/ 2 x PR x h 1 + 1/ 2 x PR x h 2 = PR( h 1 + h 2 / 2 ) Let's calculate the area of triangle PQR and the area of triangle PSR.Īrea of ΔPSR = 1/ 2 x Base x Height = 1/ 2 x PR x h 1Īrea of ΔPQR = 1/ 2 x Base x Height = 1/ 2 x PR x h 2 H₁ and h₂ are the heights of triangles PQR and PSR respectively.Īrea of quadrilateral PQRS can be calculated by adding the area of two triangles i.e. We can observe the following quadrilateral as a combination of two triangles, considering the diagonal PQ as a common base. Consider the quadrilateral PQRS given below: Let us learn to derive the area of the quadrilateral general formula.

Here, we will look at the important area formulas for quadrilaterals and how to find the area of quadrilateral. The area of a quadrilateral is the number of square units that can be formed into it. Few renowned examples of quadrilaterals are square, rectangle, trapezium, rhombus, kite, and parallelogram. There are two different types of a quadrilateral namely regular quadrilaterals and irregular quadrilaterals. Also, it has 4 edges (sides) and four vertices (corners). There are also various subcategories of convex quadrilaterals, such as trapezoids, parallelograms, rectangles, rhombi, and squares.A quadrilateral is a four-sided two-dimensional geometrical figure whose sum of all the four internal angles is 360 o. There are two main types: concave and convex.

What is the definition of a quadrilateral?Ī quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles. Angles at the intersection of the diagonals are vertically opposite. The four angles in any quadrilateral always add to 360 360°, but there are a few key properties of quadrilaterals that can help us calculate other angles. What do 4 sides of a quadrilateral add up to? The word 'quadrilateral' is derived from the Latin words 'quadri,' which means four, and 'latus', which means side. A quadrilateral is a polygon having four sides, four angles, and four vertices.
