Geometry

Many test takers, though good at Math find Data Sufficiency difficult. They are much more used to the straight forward Problem Solving pattern. The very principles behind the two question types are very different. In Problem Solving questions, our target […]

The concept of slope is extremely important so it is not sufficient to know how you calculate it using . In simple terms, the slope specifies the units by which the co-ordinate changes and the direction in which it changes […]

Today, we will look at a relatively difficult polygon question. We would like to remind you here that the concepts tested are still very simple – though we wouldn’t like to give away just exactly which concepts they are. Take […]

In today’s post, let us discuss sided polygons and the number of diagonals they have. We will discuss the following: 1. How do we find the number of diagonals an sided polygon has? 2. How many diagonals are subtended by […]

Normally, people will say – Never! But we beg to differ. Often, you would have read in our posts or heard us talk about the importance of diagrams in many Quant questions – Co-ordinate geometry, Races, some Time-Speed-Distance problems, Sets […]

We aim to solve all our Geometry questions without the use of trigonometry because many standardised tests do not require it. This question makes us feel that we need trigonometry to handle it but it is not so. In fact, […]

Test takers often ask for tips and short cuts to cut the work. So the question writer might want to award the test taker who pays attention to details and puts in the required effort. Today, we will look at […]
