GMAT Geometry Tricks

Hii sir, I Wants to get the GMAT Geometry Strategy Tricks Will you Please Provide me the Guide Lines to Solve the GMAT Geometry Questions ?

Geometry is fairly unique among GMAT Quant topics. There are many more rules you must memorize (area, perimeter, triangle ratios, etc.), and there's often a diagram accompanying the question.

the Guide Lines to Solve the GMAT Geometry Questions Are given below

1. Memorize the Rules
You can t get around it. You have to know the 30:60:90 triangle ratio. You ll be tested on the area of a circle.

There are plenty of GMAT questions that you can't fake your way through--if you don t know that basic content, you'll miss them. They can be cheap points, but only if you do the work.

2. Apply the Rules

This sounds obvious, but bear with me. It takes some time to learn all the rules, but once you know them, there isn t much that the GMAT can keep hidden

. If there are triangles in a question, there are only so many rules that could possibly apply.

If youre stuck on a geometry question, use the process of elimination. Think through all of the techniques you know that could possibly be relevant. One of them is probably what you need to use to solve the problem.

3. Look For Connections
Many GMAT geometry questions involve multiple figures. Sometimes theres a circle inscribed in a triangle; other times there are several adjacent triangles.

If there is more than one recognizable shape in a diagram, there is a connection. Look for what one of the figures tells you about the other.

Perhaps the diagonal of a square is the same as the radius of a circle. Or the height of one triangle is the hypotenuse of another. Whatever the connection, it is probably the key to answering the question.

4. Re-draw Diagrams
If there is any complexity to a diagram at all, replicate it on your scratch paper. Youll instantly get a better understanding of the figure, and you'll be able to jot down notes, such as the measure of a certain angle.

5. Mark Up Diagrams
Once youve drawn a diagram on your scratch paper, figure out all the details you possibly can. If two of the angles in a triangle are given as 70 and x, you can determine that the third angle is 180 - 70 - x, or 110 - x.

Note that on the diagram! Steps like that, even though they may seem obvious at first glance, are often the difference between solving a problem and staying stuck on it.

6. Keep an Open Mind
While most geometry problems stay within the bounds of geometry, some don't. A great example is Problem Solving #229 in the 12th edition of the Official Guide.

It sounds like a geometry question (Right triangle PQR is to be constructed in the xy-plane...) but it ends up testing combinatorics (How many different triangles with these properties could be constructed?")
