Co-ordinate Geometry - Lines Crossing X Axis or Y Axis

Today let’s learn about the cases in which lines on the XY plane cross, or do not cross, the x- or y-axis. Students often struggle with questions such as this:

Quant

Geometry - Linear Relation on the XY axis

The concepts of direct, inverse and joint variation are commonly discussed but linear relation is not discussed often. Today, we will discuss what we mean by “linearly related”.

Quant

Geometry - Parallel Lines and Transversals

Today, we will look at a Geometry concept involving parallel lines and transversals (a line that cuts through two parallel lines). This is the property: The ratios of the intercept

Geometry - Area of Similar Triangles

Recall the important property that we discussed about the relation between the areas of the two similar triangles – if the ratio of their sides is ‘k’, the ratio of their areas will be k^2.

Geometry - Regular and Irregular Polygons

Let’s discuss polygons today. While many of the classic shapes – triangles, rectangles, and squares, most notably – count as polygons and their formulas have been burned in our minds since elementary...

Geometry - Right Triangles, Rectangles and Looking for Clues!

To excel in GMAT, we can take a leaf out of Sherlock Holmes' book and learn to notice little things. There is a good reason to do that – there are little clues in some questions that the test maker un...

Geometry - Identifying Similar Triangles

What we would like to discuss today are situations where most people do not think about similar triangles but if they do, it would make the question very easy for them. But before we do that, we would...

Geometry - Median, Altitude and Angle Bisector in Special Triangles

No concept group on GMAT geometry questions is more important than triangles, and no discussion of triangles on the GMAT would be fully comprehensive without covering medians, altitudes, and angle bis...

Geometry - Rectangle Inscribed in a Circle

The biggest problem test takers complain about is that they are unable to figure out the topic the problem is testing. When this happens, they don't know how to start working on the problem.

Geometry - Area of Triangle on Co-ordinate Axis

We often come across people wondering whether they should learn up the many formulas in permutation/combination, co-ordinate geometry etc. Our take on the question is a flat ‘No’.
