Not sure how or what to study? Confused by how to improve your score in the shortest time possible? We've created the only Online GMAT Prep Program that identifies your strengths and weaknesses, customizes a study plan, coaches you through lessons and quizzes, and adapts your study plan as you improve. I’ll talk more about what this actually means when I go over some geometry sample questions. You’ll need to know how to combine your geometry knowledge with knowledge of other concepts (like number properties, for instance) to get at the correct answer. Geometry questions make up just under a quarter of all questions on the GMAT quant section. As with all GMAT quant questions, you won’t just need to know how to apply geometry principles in isolation. You’ll find geometry concepts in both data sufficiency and problem-solving questions. In the next section, I’ll talk about the geometry concepts that you’ll actually find on the GMAT. The GMAT only covers a fraction of the geometry that you probably studied in high school. If you feel like you’ve forgotten a lot of the geometry that you learned in high school, don’t worry. Finally, I’ll talk about how to study for the geometry you’ll encounter on the GMAT and give you tips for acing test day. Then, I’ll show you four geometry sample questions and explain how to solve them. Next, I’ll give you an overview of the most important GMAT geometry formulas and rules you need to know. In this article, I’ll be giving you a comprehensive overview of GMAT geometry.įirst, I’ll talk about what and how much geometry is actually on the GMAT. If you’ve forgotten a lot of your high school geometry rules or are just in need of a refresher before taking the GMAT, then you’ve found the right article. What we need to remember for the formula, though, is that π is often rounded to 3.14.If you’re like me, you probably spent a lot of time in high school memorizing the difference between sine and cosine and sighing over long, multi-step proofs, only to forget all of this hard-earned knowledge the second that classes dismissed for break.
Pi, or π, is the ratio of the circumference to the diameter and is an irrational number. The height of a trapezoid, like the height of a parallelogram, is the distance between the two bases The height of a parallelogram goes from one base to the other and has to meet both bases at right angles.Īrea of Trapezoid = ½(Base 1 + Base 2) × Height So, the height has to square up with the base. The height of a triangle is the length of a line that connects the base and vertex and is perpendicular to the base. We're way too lazy to write out "side length" so we're going to abbreviate it as s, which makes Area = s 2. Since a square's base and height are equal, the area of a square is also side length times side length, or side length squared.
Let's go over these area formulas one more time.Ī square, technically speaking, is a rectangle (don't remind the rectangle, it's a little sensitive), so we can use the formula for the area of a rectangle to find the area of a square.
