RS Aggarwal Solutions Class 8 Chapter-16 Parallelograms (Ex 16A) Exercise 16.1

Q: 1. What are special Parallelograms according to RS Aggarwal Solutions Class 8 Chapter-16 Parallelograms?

Class 8 students are taught 5 major Special parallelograms-Square and Rectangle: Squares and rectangles have similar properties to a parallelogram. Both have equal opposite sides which are parallel to each other. Diagonals of both square and rectangle bisect each other. Rhombus: Rhombus is a type of parallelogram where all sides are congruent or equal to one another.Rhomboid: Rhomboids have their opposite sides parallel to each other and adjacent sides are of unequal lengths. Trapezium: Trapezium occurs when one parallel side and the other two sides of a parallelogram become non-parallel.

A parallelogram is a quadrilateral whose 2 opposite times are equal and parallel. In a parallelogram, opposite sides and opposite angles are also equal.

Types of Quadrilaterals

The Quadrilaterals are classified based on sides or angles, and they are as follows:

Square
Rectangle
Rhombus
Trapezium
Parallelogram
Kite

Elements of a Parallelogram

Then 4 elements of a parallelogram are-

2 Pairs of Opposite Sides

The opposite sides of a parallelogram are always of equal length.

4 Pairs of the Adjacent Side

The opposite angles of a parallelogram are always equal and the sum of all angles is always 360°.

2 Pairs of Opposite and Equal Angles

The adjacent angles in a parallelogram are always supplementary.

4 Pairs of Adjacent Angles

The diagonals of a parallelogram always bisect each other at their point of intersection.

The sum total of any 2 adjacent angles is 180°.
Diagonals of a rhombus always bisect one another at 90°.
A rhombus has 2 lines of symmetry.
A rhombus can never have an inscribing circle.

5. How to score well in Class 8 Chapter-16 Parallelograms?

Quadrilaterals chapter of class 8 has many properties to understand and complex formulae to remember. To score well in this chapter and part of Parallelogram, class 8 students must solve a lot of questions. Solving sample papers from books like RS Aggarwal and Rd Sharma contains many questions from previous year's question papers that will help the class 8 student to understand the pattern of questions asked. It also sets them up to solve an exam paper within a time limit. Occasional revision of important formulae and concepts is a must to hold on to the information for a long time.
