    GMAT Geometry Topics<\/h2>\n

    In the GMAT, Geometry constitutes a number of topics. They are as follows (this list is in accordance with the GMAT Official Guide):<\/p>\n

      \n
    1. Lines and Angles<\/li>\n
    2. Convex Polygons<\/li>\n
    3. Triangles<\/li>\n
    4. Quadrilaterals<\/li>\n
    5. Circles<\/li>\n
    6. Rectangular solids and cylinders<\/li>\n
    7. Coordinate Geometry<\/li>\n<\/ol>\n

      Examples – GMAT Geometry Questions with Answers and explanations<\/h2>\n

      Question 1:<\/h3>\n

      If a convex polygon has 5 diagonals, what is the sum of internal angles of the polygon?<\/p>\n

      Approach:<\/h3>\n

      The number of diagonals is equal to the total number of lines formed by joining any two vertices minus the number of sides.<\/p>\n

      Hence, the number of diagonals = nC2 – n = n(n-1)\/2 – n = n(n-3)\/2 = 5<\/p>\n

      n(n-3) = 10<\/p>\n

      n = 5<\/p>\n

      Hence, the sum of internal angles = (5-2) x 180 = 540 degrees.<\/p>\n

      Question 2:<\/h3>\n

      The length of the equal sides of an isosceles triangle is 6 cm. What is the maximum possible area of the triangle(in square centimetres)?<\/p>\n

      Approach:<\/h3>\n

      Let us assume that one of these 6 cm sides is the base and the angle that the other 6 cm side makes with the base is k degrees.<\/p>\n

      Now, we know that the area of a triangle whose 2 adjacent sides are known and the enclosed angle is known can be calculated as:<\/p>\n

      Area = (1\/2)*a*b*sin(k)<\/p>\n

      a = First side<\/p>\n

      b = Second side<\/p>\n

      k is the angle enclosed.<\/p>\n

      Now, a and b are fixed as 6 cm each<\/p>\n

      If sin k is maximum = 1, the value will be maximum.<\/p>\n

      Hence, the maximum possible area = (1\/2) x 6 x 6 = 18<\/p>\n

      Question 3:<\/h3>\n

      What is the radius of a circle C?<\/p>\n

      Statement 1: The ratio of the circumference and the diameter = 3.14<\/p>\n

      Statement 2: The ratio of the area and the circumference is 5.4 units.<\/p>\n

      Approach:<\/p>\n

      Statement 1: Circumference = 2 * pi * r<\/p>\n

      Diameter = 2 * r<\/p>\n

      Ratio = pi<\/p>\n

      The statement does not add any value to the information that is provided.<\/p>\n

      Statement 2: The ratio of the area and the circumference is 5.4 units.<\/p>\n

      pi * r * r \/ (2 * pi * r) = 5.4<\/p>\n

      r = 10.8 units.<\/p>\n

      Hence, Option B – Statement 1 alone is not sufficient, Statement 2 alone is sufficient is the correct choice.<\/p>\n

      Note:<\/h3>\n

      Though these examples provide a good sense of what type of GMAT Geometry questions you can expect, in no way do they represent the exhaustive list of concepts required for the Quantitative section of GMAT.<\/p>\n

      Tips to keep in mind:<\/h3>\n
        \n
      1. Try to take some time out from the Problem-Solving Geometry questions so that you can use that time to solve the tricky Data Sufficiency Geometry questions.<\/li>\n
      2. Do not get stuck in a question for long. If you find yourself trapped in a question for long, take a guess and move on.<\/li>\n
      3. Read the units(if any) carefully.<\/li>\n
      4. Look out for negation words. For example: Which of the following are NOT possible values of x?<\/li>\n
      5. Some questions can be solved faster by the use of options. Make sure you don’t solve these questions in a conventional way.<\/li>\n<\/ol>\n
