RD Sharma Solutions for Class 8 Maths Chapter 17: Understanding Shapes – III (Special Types of Quadrilaterals)

The 17th chapter of the RD Sharma book for Class 8 maths is on special quadrilaterals. Class 8 pupils have a limited understanding of quadrilaterals. These include forms like square, rectangle, trapezium, pentagon, etc. This chapter focuses on creating concepts of various quadrilaterals using the data provided. Maths Chapter 17 Understanding Shapes – III (Special Types of Quadrilaterals) offers a wealth of information about quadrilateral definitions and attributes of many types of quadrilaterals. Because these quadrilaterals are said to be special, the characteristics of these quadrilaterals are taught to the students. These properties have a vast importance in the study of geometry. Trapezium, isosceles trapezium, parallelogram, rhombus, rectangle, and square are all examples of quadrilaterals. In this chapter, we will mostly look at the characteristics of all these quadrilaterals. These quadrilaterals are called special quadrilaterals because they have certain characteristics (in terms of diagonals, angles, angle relationships and orientation of sides) that make them uniques from the rest of the quadrilaterals

The concept of quadrilaterals includes sides, adjacent sides, opposite sides, angle, adjacent angle, and opposite angles. The types of curves such as closed curves and simple curves. Further in RD Sharma Maths chapter 17 Understanding Shapes – III (Special Types of Quadrilaterals), The properties for a parallelogram include; The adjacent angles in a parallelogram are supplementary, the diagonals of a parallelogram bisect each other at the point of intersection, the diagonals of a rectangle are of equal length, the diagonals of a rhombus are perpendicular bisectors, the diagonals of a square are perpendicular bisectors of each other, the opposite angles of a parallelogram are of equal measure, the opposite sides of a parallelogram are of equal length. The rhombus, kite, rectangle and square have similar properties, elaborated in the chapter.
