Here is a question in coordinate geometry. The primary idea tested by this question is one's understanding about equations of straight lines. Set S contains points whose abscissa and ordinate are both natural numbers. Point P, an element in set S has the property that the sum of the distances from point P to the point (8, 0) and the point (0, 12) is the lowest among all … [Read more...] about GMAT Coordinate Geometry

## GMAT Geometry: Acute Angled Triangles

Geometry concepts such as basic properties of triangles and how to find if a given triangle is a right triangle or an acute angled triangle or an obtuse angled triangle are often tested in GMAT.Here is a question using two basic rules about triangles.QuestionIf 10, 12 and 'x' are sides of an acute angled triangle, how many integer values of 'x' are possible?(A) 7(B) 12(C) 9(D) … [Read more...] about GMAT Geometry: Acute Angled Triangles

## Number of diagonals in convex polygon : GMAT

Any n-sided convex polygon with more than 3 sides will have n(n-3)/2 diagonals. For instance, let us look at a square. A square has 4 sides and 2 diagonals. Let us apply this formula with n = 4. We get 4(4-3)/2 = 2 diagonals. Here is a question on finding the number of diagonals. If a n-sided convex polygon has 14 diagonals, how many sides does the polygon … [Read more...] about Number of diagonals in convex polygon : GMAT
