Chapter 06 – Direct and Inverse Variation
Variation means change. With direct variation, numbers change proportionately in the same direction, while with inverse variation, they change in opposite directions. In this chapter, we will earn how to solve direct and inverse variation problems, explore their definitions, and work examples to understand the equations and techniques for solving them. Also, we learn to find the continued ratio for two or more ratios.

Chapter 08 – Algebraic Expressions
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The algebraic equations which are valid for all values of variables in them are called algebraic identities. In this chapter, we will learn to perform operations on polynomials and to factorize an algebraic equation by using identities.

Chapter 09 – Linear Equations
Linear equations are equations having variables with power 1. ax+b = 0 is an example with one variable where x is the variable, and a and b are real numbers. In this chapter, we will learn the definition, type of solutions, and how to solve these equations with one variable and two variables using different methods along with examples.

Chapter 10 – Fundamentals of Geometry
Geometry is the study of different types of shapes, figures, and sizes in Maths or real life. In geometry, we learn about different angles, transformations, and similarities in the figures. It is important to know and understand some basic concepts. We will learn about working in different numbers of dimensions, and about some of the most fundamental concepts in geometry, including points, lines, and planes.

Chapter 11 – Practical Geometry
The practical Geometry chapter will teach you about lines and to construct two-dimensional given different kinds of measurements. A quadrilateral is a closed two-dimensional shape that has four sides and four angles. Any four-sided closed shape such as square, rectangle, rhombus, parallelogram, trapezium, etc. And a closed two-dimensional shape that has 3 sides and 3 angles is known as a triangle.

Chapter 13 – Information Handling
Frequency distribution, in statistics, is a graph or data set organized to show the frequency of occurrence of each possible outcome of a repeatable event observed many times. And, a pie chart is a way of representing data in a circular graph. Pie slices of the chart show the relative size of the data. In this chapter, we will learn to construct the frequency distribution table, some new pie chart vocabulary, and learn to construct the pie chart to represent the data.

Construction of a Parallelogram (Adjacent Side and Diagonal Given)

Let us discuss the working rule to construct a parallelogram when the measures of two adjacent sides and a diagonal of a parallelogram are given.
 
Example:
Construct a parallelogram DUCK with DU = 8 cm, UC = 6.5 cm and DC = 11 cm.
 
Construction:
 
Step 1: Draw a line segment DU = 8 cm.
 
Step 2: With D and U as centers, draw two arcs of radii 11 cm and 6.5 cm respectively such that they intersect each other at C.
 
Step 3: Join DC and UC.
 
Step 4: With C and D as centers, draw two arcs of radii 8 cm and 6.5 cm respectively such that they intersect each other at K.
 
Step 5: Join DK and CK.
 
Step 6: DUCK is the required parallelogram. The measure of KE gives the height of the parallelogram DUCK.

 

Construct a parallelogram when two consecutive sides and a diagonal are given

image
Construct a parallelogram ABCD in which AB = 6 cm, BC = 4.5 cm and diagonal AC = 6.8 cm.

  1. Draw AB = 6 cm. 
  2. With A as center and radius 6.8 cm, draw an arc.
  3. With B as center and radius 4.5 cm draw another arc, cutting the previous arc at C. 
  4. Join BC and AC. 
  5. With A as center and radius 4.5 cm, draw an arc. 
  6. With C as center and radius 6 cm draw another arc, cutting the previously drawn arc at D. 
  7. Join DA and DC. 

Then, ABCD is the required parallelogram.
