SAT Tip of the Week: Hidden Shapes in Math Problems  [#permalink]

 FROM Veritas Prep Admissions Blog: SAT Tip of the Week: Hidden Shapes in Math Problems Some of the most difficult kinds of problems in the math section of the SAT are the problems where there doesn’t seem to be enough information present to solve.  Fear not brave test-taker! Often times, a problem that seems to be lacking simply has information hidden somewhere in the question. But like the great detectives of the past, it is possible to use our wits to find this information.  The first step is to know the common shapes hidden in SAT math questions. 1. For non-right triangles, look to draw a height. Here is an example problem:The triangle shown here is isosceles.  If the angle measure of the vertex opposite one of the sides is 60 degrees, what is the area of the triangle in terms of x? This is a surprisingly simple problem when you get down to it. However, it does require us to put on our Sherlock Holmes cap for a moment.  First, lets fill in what we know.  The fact that this is an isosceles triangle with one angle measuring 60 degrees should quickly tip us off that this is an equilateral triangle. Now the information we are looking for is the area, which is ½ the triangle’s base times the triangle’s height. It would then behoove us to draw a height in our triangle above.If we recall the rules of the special triangles (30-60-90, 45-45-90), we will realize that the height, in terms of x, is simply the small side of the triangle times the square root of 3 so the height would be ½ x√3.  Plugging this information back into the area equation, the area of the whole triangle would be ½ x (½ x√3) which simplifies to (½ x)²√3.  Once we draw in the height this becomes a fairly standard area problem: how useful finding the hidden pieces can be! 2. When possible, draw radii and diameters. One of the most common places information is hidden is within the relationship between the length of radii and other measurements given in a problem.  Here is an example problem:Two congruent circles are inscribed within a rectangle. What is the length of the diagonal of this rectangle? This problems is more straight forward than the first, but it also requires a little detective work. The first step is to draw some diameters and radii, just to see if it helps us notice anything.AHA! This small act has yielded a lot of information.  We see that the the diameter is equal to the small side of the rectangle and the length is equal to twice the diameter of the circle. This means the long side is twelve units and the diagonal can be calculated by using the Patagonian theorem.  6² + 12² = x²x² = 180x = √180There are many other ways the SAT can hide information from our sight, but these are two important tools in helping us to fill in some of the information that might not have been provided.  Though it can be difficult to see what pieces are missing, with a little practice, you will be a first rate detective.  Happy studying!Plan on taking the SAT soon?

Find the Correct Answer for Diagonals of a Polygon in This G  [#permalink]

### Show Tags

07 Jul 2014, 09:00
 FROM Veritas Prep Admissions Blog: Find the Correct Answer for Diagonals of a Polygon in This GMAT Question In today’s post, we will give you a question with two solutions and two different answers. You have to find out the correct answer and explain why the other is wrong. But before we do that, let’s give you some background.Given an n sided polygon, how many diagonals will it have?An n sided polygon has n vertices. If you join every distinct pair of vertices you will get nC2 lines. These nC2 lines account for the n sides of the polygon as well as for the diagonals.So the number of diagonals is given by nC2 – n.nC2 – n = n(n-1)/2 – n = n(n – 3)/2Taking quick examples:Example 1: How many diagonals does a polygon with 25 sides have?No. of diagonals = n(n – 3)/2 = 25*(25 – 3)/2 = 275Example 2: How many diagonals does a polygon with 20 sides have, if one of its vertices does not send any diagonal?The number of diagonals of a 20 sided figure = 20*(20 – 3)/2 = 170But one vertex does not send any diagonals. Each vertex makes a diagonal with (n-3) other vertices – it makes no diagonal with 3 vertices: itself, the vertex immediately to its left, and the vertex immediately to its right. With all other vertices, it makes a diagonal. So we need to remove 20 – 3 = 17 diagonals from the total.Total number of diagonals if one vertex does not make any diagonals = 170 – 17 = 153 diagonals.We hope everything done till now makes sense. Now let’s go on to the part which seems to make no sense at all!Question: How many diagonals does a polygon with 18 sides have if three of its vertices, which are adjacent to each other, do not send any diagonals?Answer: We will use two different methods to solve this question:Method 1: Using the formula discussed aboveNumber of diagonals in a polygon of 18 sides = 18*(18 – 3)/2 = 135 diagonalsEach vertex makes a diagonal with n-3 other vertices – as discussed before.So each vertex will make 15 diagonals.Total number of diagonals if 3 vertices do not send any diagonals = 135 – 15*3 = 90 diagonals.Method 2:The polygon has a total of 18 vertices. 3 vertices do not participate so we need to make all diagonals that we can with 15 vertices.Number of lines you can make with 15 vertices = 15C2 = 15*14/2 = 105But this 105 includes the sides as well. A polygon with 18 vertices has 18 sides. Since 3 adjacent vertices do not participate, 4 sides will not be formed. 15 vertices will have 14 sides which will be a part of the 105 we calculated before.Total number of diagonals if 3 vertices do not send any diagonals = 105 – 14 = 91Note that the two answers do not match. Method 1 gives us 90 and method 2 gives us 91. Both methods look correct but only one is actually correct. Your job is to tell us which method is correct and why the other method is incorrect.Karishma, a Computer Engineer with a keen interest in alternative Mathematical approaches, has mentored students in the continents of Asia, Europe and North America.
