Geometry for GMAT Exam
Join me in this miniseries of videos on geometry for the GMAT exam.
In this first video, we will tackle some advanced geometry questions
that will help you in your exam. Over the next three videos, I will
guide you through everything you need to know for geometry. Even
if you are the type of person who can get a score of 48, 49, or 50 on
the GMAT exam, geometry questions can be tricky for a lot of
people. Having multiple methods and approaches is a huge
advantage in the exam.
Multiple methods and techniques will help you in the GMAT. If you
limit yourself to only one way of solving a problem, the exam can be
difficult and time-consuming. Knowing different ways to approach
the problem will help you solve the question efficiently. By the end
of this video, I’ll have covered nine questions, and you’ll be able to
handle all kinds of coordinate geometry questions that can come
your way in the GMAT exam. So, without further ado, let's get
started with the first question.
Question:
Give yourself a few minutes to solve this:
Example:
Afterwards, we'll discuss the background to the question and the
perfect solution approach.
The distance from point A to point B is the hypotenuse with a length
of the square root of 50. If we square it and subtract the square of
the horizontal distance, d, and the square of the vertical distance, 7,
we obtain the length of the hypotenuse. The vertical distance is the
difference between 8 and 1, which is 7. To find the x coordinate of B,
we can check which answer has a 0 or a 2. In the first data
sufficiency question, we need to build a triangle and use Pythagoras
to find the missing information. It's important to create a diagram
and fill in the known information. Moving on, let's discuss slopes,
intercepts, and the equation of a line. For now, we'll ignore the
previous information, which isn't sufficient to answer the question.
We can cross out options A and D. The second piece of information
tells us the slope of the line is 2/5. This means that for every 5 units
we move horizontally to the right, we move 2 units upwards. A
positive number indicates a positive slope, meaning the line slopes
upwards as we move from left to right.
