If you are also a parent of a kid studying in a lower grade and looking for trustable online educational platforms, you can enroll them in SplashLearn. Therefore, parents and teachers can teach quadrilaterals to their children without much effort. This easy and unique method of learning quickly grabs the attention of young learners. In SplashLearn, your child can learn about quadrilaterals in a fun and gaming way. This article has taught us that a quadrilateral is a closed-shape polygon with four sides, four angles, and four verticals. Therefore, perimeter of quadrilateral is:Įxample 3: If the area of a rhombus is 60 square units and its height is 6 units, what will be the value of its base? Given, the sides of a quadrilateral are 6 cm, 8 cm, 10 cm, and 12 cm.
We know that the sum of all the angles of a quadrilateral is 360°.Įxample 2: What will be the perimeter of a quadrilateral with sides 6 cm, 8 cm, 10 cm, and 12 cm? Find the missing angle in the given quadrilateral. The formulas to find out the area of different types of quadrilaterals are shown below: Solved Examples on QuadrilateralĮxample 1. The area of the quadrilateral is the region enclosed by all its sides. The formula for the perimeter of some of the common quadrilaterals is given below: Quadrilateral Name Perimeter of quadrilateral ABCD = AB + BC + CD + DA If ABCD is a quadrilateral then its perimeter will be: AB + BC + CD + DA This means the perimeter of a quadrilateral equals the sum of all the sides. The perimeter of a quadrilateral is the length of its boundary. A quadrilateral is convex if the line segment joining any of its two vertices is in the same region. the line segment joining the vertices is not a part of the same region of the quadrilateral.Ĭonvex quadrilaterals: In convex quadrilaterals, each interior angle is less than 180°. Here’s a list of the types of quadrilaterals with their name, pictures, and properties: Concave and Convex QuadrilateralsĬoncave quadrilaterals: In concave quadrilaterals, one interior angle is greater than 180°.Ī quadrilateral is called a concave quadrilateral if at least one diagonal, i.e. Square, Rectangle, and Rhombus are also Parallelograms. Quadrilaterals can be classified into Parallelograms, Squares, Rectangles, and Rhombuses. Square is the only quadrilateral that satisfies all these conditions. A regular quadrilateral must have 4 equal sides, and 4 equal angles, and its diagonals must bisect each other. A quadrilateral can be regular or irregular.The sum of all interior angles is 360°.Some properties are common to all quadrilaterals. There are many real-life quadrilateral examples: cards, chess boards, traffic signs, etc. The above images are some non-examples of quadrilaterals. Shapes that do not have four sides or four angles or have curved sides or are open shapes are non-examples of quadrilaterals. AC and BD are the two diagonals of the quadrilateral ABCD.A, B, C, and D are the four vertices of the quadrilateral ABCD.AB, BC, CD, and DA are the four sides of the quadrilateral ABCD.∠A, ∠B, ∠C, and ∠D are the four angles of the quadrilateral ABCD.
