Look closely at the minute and the hour hand of the wall clock. You will observe that both these hands make an angle between them. What is the angle? An angle in Geometry is a shape, formed by two lines or rays diverging from a common point. They help us to figure out the degree …
When you look at the objects around you, they all have a specific shape. Some are triangular, some rectangular and so on! The field of mathematics that deals with shapes, sizes, the position of figures, and properties, is called ‘Geometry’. The world of geometry extends wider. A simple triangle has different types, whereas a rectangle …
Statistics is a branch of mathematics which deals with graphs, pie graphs, histograms and many more mathematical elements. In lower grades, we have already mastered skills in bar graphs, pie graphs, histograms and frequency polygons. In this chapter, we will move forward to advanced learning techniques of statistics. Here, in this lesson, you will encounter …
You have 10 numbers ranging from 1 to 10, which are randomly arranged. These numbers make up your data. Now, if asked to find the smallest and the biggest number, you would simply arrange your data in an ascending order and provide your answer. This process is referred to as ‘Data Analysis’. Now to find …
Imagine you are in a supermarket to take milk and eggs, but you are also in a hurry. Now if you go on to search the entire place, you are going to be late for sure. So what can be done? Well, how about asking a store representative for guidance? They will direct you at …
We have come across many shapes such as circle, square, triangle and the list goes on! To our surprise, the triangle holds a special place in maths. And why is that so? That’s because a complete branch of mathematics called ‘Trigonometry’ is committed to analysing triangles. In fact, the word ‘Trigonometry’ itself gives us an …

Mathematics is a mystery for a few! Passion for the rest. Every new concept in Math opens up a plethora of new roads to be travelled. Let us today travel one such road named “Sets” and get to know what it has in store for us!
Ever wondered, why do meteorologists use the weather patterns to predict the chances of rain? Or how can we predict the chances of passing, in an examination, based on our performance? These ‘Chances’ that we are referring to, are nothing but ‘Probability’. In weather forecast, they check the ‘Probability of rain’, while after an examination …
The world of numbers is infinite and interesting. Till now, we have understood the concepts of natural numbers, whole numbers, integers, and rational numbers. But now the question is, are all these numbers real? That question must have surely taken your breath away, but don’t worry. In this chapter, we take a look at the …
