Tell the name of the regular polygon which has i 6 sides ii 3 sides iii 4 sides Ans. What is Closed curve and Open curve Closed curve is a figure in the plane with no end points. For a polygon to be regular, it must also be convex. All square are rectangles but all rectangles are not square. The diagonals of a parallelogram bisect each other.

NextVertices A and C, B and D are opposite vertices. So, sum of angles is equal to:-No. It does not matter with which letter you begin as long as the vertices are named consecutively. The dotted lines are drawn additionally to help you. Students and parents can download free a collection of all Understanding Quadrilaterals study material carefully compiled by the best teachers. When they are on the go for scoring more marks for the main subjects, their performance level and the marks got greatly reduced in English.

These solutions have been solved and reviewed by a specialized team of our subject experts. . Or use it to create really cool photo slideshows - with 2D and 3D transitions, animation, and your choice of music - that you can share with your Facebook friends or Google+ circles. Obtain the value for each of the exterior angle of a regular polygon with i 10 sides ii 25 sides Ans. Quadrilaterals : Definition : Definition A plane figure bounded by four line segments is called a quadrilateral.

NextThe diagonals of a rhombus are perpendicular bisectors of one another. The adjacent angles are supplementary and the diagonals bisects each other ; but they are not equal. Explain why W is equidistant from P, Q and R. So, subtract 2 from it, and we get 1. Vertices A and B, B and C, C and D, D and A are consecutives vertices. Find the measure of each of the angles of the parallelogram.

NextOr use it to upload your own PowerPoint slides so you can share them with your teachers, class, students, bosses, employees, customers, potential investors or the world. All squares are parallelograms as opposite sides are parallel and opposite angles are equal. Calculate the number of sides a regular polygon will have if the value of an exterior angle is 36°? A regular polygon having each of its interior angles 144°. The topics and sub-topics in Chapter 3 Understanding Quadrilaterals 3. In it we first have to seethe number of sides of a polygon, then subtract2 from it and multiply the result by 180 to find itstotal angle sum. This means, one of the sides starts where the other one ends. Special Property The diagonals of a rhombus are perpendicular bisectors of one another Rectangle A rectangle is a parallelogram with equal angles Property 1 Each angle is of 90 0 Property 2 The diagonals of a rectangle are of equal length Square A square is a rectangle with equal sides.

NextWe can classify polygons according to the number of sides or vertices. A pentagon is a five-sided polygon. Identify the below diagrams based on the following category a Concave polygon b Simple curve c Convex polygon d Simple closed curve e Polygon Ans. Which of its two sides are parallel? Q4 Check the table Each diagram is separated into triangles and the sum of the angles is taken out from that Find out the angle sum of convex polygon with following number of sides? A hexagon is a six-sided polygon. It has all the properties of a parallelogram and also that of a kite. We know a polygon is a simple closed figure made up of only line segments. And after multiplying 1 with 180 we get 180 i.

NextIn square the diagonals:- bisect one another; are of equal length; are perpendicular to one another. English is a global language, so it is very important to learn that subject as it can help. Explain why a rectangle is a convex quadrilateral. While students have to cover a lot of topics, the given here covers all the questions and concepts related to this chapter and helps students understand the topics in an easy manner. There are exactly two distinct consecutive pairs of sides of equal length.
