As discussed before, now that we’ve talked about the basic triangles, we can start looking at how the GMAT can make problems difficult by embedding triangles in other figures, or vice versa. Here are just a few examples, which include triangles within and outside of...
Triangles, and Geometry in general, are something you need to master as much as you can before your GMAT exam. It can seem complicated in the beginning, but once you start working with different geometric objects and its shapes, thing will definitely get easier. The...
As promised, we will now connect the 30-60-90 triangle to the equilateral triangle, specifically its area. There is a formula for the area of an equilateral triangle as it relates to the length of its side s, and it is as follows: But more likely than not for the...
45-45-90 Right Triangle Another of the commonly tested triangles on the GMAT is the 45-45-90, also known as the isosceles right triangle. Know that term, as it could appear by name in a question. As shown in the above diagram, the side lengths of this triangle always...
Right Triangle Identities: 3-4-5 Right triangles always adhere to the same basic relationship, reflected by the Pythagorean Theorem, or a² + b² = c², where a, b, and c match the triangle sides as pictured above. c always represents the longest side, called the...
