Also, in the second exercise, you are asked to find the roots of quadratic equations using factorization. The main topics in this chapter are solutions by factorization and solutions of a quadratic equation using the square. There are four exercises described in the chapter. These exercises are divided further into various questions where you need to find a term. In this chapter, you will learn how to find the nth term.

Alongside you will also find the sum of n consecutive terms. This is because it has six exercises on it.

## NCERT Solutions

The solution bank includes the subjects ranging from Maths and Science for class 6 and 7, which is expanded to cover even English, Hindi and Social Science for class 9 and For class 11 and 12, our focus is predominantly on providing step by step solution to problems and questions from Maths, Physics, Chemistry, and Biology.

Vedantu Gives You the Competitive Edge: We believe that every student has the right to education and to make this motto concrete, we provide many other solutions out of which NCERT Solution is just a part.

We at Vedantu intend to get the best out of all our students by helping them with all the possible ways so that they can excel in their exams and get good grades. The two rays are called the arms or sides of the angle and the common initial point is called the vertex of the angle. Sense of an Angle: It is defined as the direction of rotation of the initial side into the terminal side.

If the direction is anti-clockwise, then the sense is said to be positive and if the direction is clockwise, then the sense is negative. Both the lines may or may not be parallel to each others.

They can be at any angle or orientation on the plane, we can translate the line or rotate the line. In the figure above, there are two congruent line segments. They are laying at different angles. If we drag any of the four endpoints, the other segment will change length to remain congruent with the one we are changing.

In the given figure "AB is congruent to PQ". You could say "the length of line AB equals the length of line PQ".

But in geometry, it is "line segments AB and PQ are congruent". In any case two rays and lines cannot be congruent to each other because they do not have both end points defined, and so have no definite length.

Ratios are written with the : symbol. We can understand ratio in different form as 1. Since a ratio is only a comparison or relation between quantities, it is an abstract number. For instance we consider the ratio of 10 km to 5 km is only 2, not 2 km.

## NCERT Solutions

Because it is unit less. Ratios can be written as fractions. They also have all the properties of fractions that you have already learned in the previous part of this chapter. The ratio of 10 to 5 should be stated as 2 to 1, but common usage has shortened the expression of ratios to be called simply 2.

If two quantities cannot be expressed in terms of the same unit, there cannot be a ratio between them. A man has to travel 50 k. In this case we will not take the ratio of these quantity. Because we know that the distance covered divided by time is velocity this is not ration quantity. Clearly, the ratio of two quantities is equivalent to the fraction that one quantity is of the other. But what if we divide two integers , this is known as rational numbers. The word comes from "ratio" for rational numbers.

The first section will explain the meaning of the term "perimeter. The second section will explain the meaning of the term "area.

We can find the perimeter of any figure like square, rectangles, any polygon.The explanation of the various topics is done in an organised and simple manner in NCERT Solutions for Class 10 Maths PDF so as to make it easy for the students to understand the concepts in clear light. Starting from the basics, that is the definition of Circle. The sixth exercise has two questions.
