if nothing is specified about the lengths, then any lengths may be the longest or shortest lengths of the diagram.\u00a0 It also means that any angle that is not marked could be acute, right, or obtuse.\u00a0\u00a0 For example, if this diagram appears without further comment &#8212;<\/p>\n<p><a href=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img5.png\"><img decoding=\"async\" class=\"alignnone size-full wp-image-12658\" src=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img5.png\" alt=\"\" width=\"239\" height=\"232\" \/><\/a><\/p>\n<p>\u2026. then it is cruelly and deceitfully trying to tempt you into believing that it is really a square.\u00a0 If this were a square, then you would know a whole boatload of things (four congruent sides, four right angles, congruent &amp; perpendicular diagonals, etc.)\u00a0 The great unwashed masses taking the GRE will fall into this erroneous assumption, and all its implications, like lemmings running to the sea.\u00a0 In fact, because the diagram specifies no lengths or angles, it could be any one of the following:<\/p>\n<p><a href=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img6.png\"><img decoding=\"async\" class=\"alignnone wp-image-12659\" src=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img6.png\" alt=\"\" width=\"627\" height=\"142\" srcset=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img6.png 871w, https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img6-300x67.png 300w\" sizes=\"(max-width: 627px) 100vw, 627px\" \/><\/a><\/p>\n<p>You always have to have your visual imagination warmed up for possible alternatives, with different lengths and different angles.\u00a0 Any angle could be the largest or smallest angle.\u00a0 Any side could be the largest or smallest side.\u00a0 The shape could look not even vaguely like the explicit diagram that appears.\u00a0 That&#8217;s all fair game in the GRE&#8217;s blanket statement: &#8220;no diagram drawn to scale.&#8221;<\/p>\n<p>If angles appear to be right angles, you can&#8217;t assume they are right angles unless the test says so, or unless a little &#8220;perpendicular square&#8221; appears in the diagram.\u00a0 For example, in #1 above, the text specifies that the figure is a rectangle, so this means you can assume it has all the properties of rectangles (four right angles, congruent opposite sides, etc.)\u00a0 In #2, \u2220EGF is marked with the little perpendicular square, so we are guaranteed that \u2220EGF = 90\u00b0.\u00a0 If nothing is marked or specified, you are falling into a trap to assume that an angle that looks right in the diagram truly is right.<\/p>\n<p>If lengths appear equal, they may not be.\u00a0 If JK appears longer than WX, then the relationship may be that way, or they may be equal, or it may be that WX\u00a0 is in fact longer that JK. \u00a0If lines appear parallel or perpendicular, you cannot assume either if it&#8217;s not specified. \u00a0You should always be suspicious about a GRE geometry diagram, and the less that is specified in words, the more suspicious you should be.<\/p>\n<p>&nbsp;<\/p>\n<h2>What you <em>can<\/em> assume on GRE geometry problems<\/h2>\n<p>The most fundamental thing you can assume about any geometric diagram: <strong><em>any line or line segment that looks straight, is straight<\/em><\/strong>.\u00a0\u00a0 For example, in problem #2 above, we are absolutely guaranteed that D-E-F are collinear and that C-E-G are collinear &#8212; that those two are straight lines with no &#8220;hidden bend&#8221; at point E.\u00a0 If it looks straight, it is straight.<\/p>\n<p>BTW, don&#8217;t confuse &#8220;straight&#8221; (meaning, &#8220;lying in a line, collinear&#8221;) with &#8220;horizontal.&#8221;\u00a0 Many people say &#8220;straight&#8221; when they mean &#8220;horizontal&#8221;, and this is a 100% wrong mistake that leads to a great deal of confusion.\u00a0 For example, you must assume a line on the GRE is &#8220;straight&#8221;, but you absolutely cannot assume it is &#8220;horizontal&#8221; if that is not stated.<\/p>\n<p>If you are told a shape in a GRE diagram is a polygon in general or a particular kind of polygon (triangle, rectangle, etc.), then you can assume<\/p>\n<p>(a) it is a closed shape:<\/p>\n<p><a href=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img7.png\"><img decoding=\"async\" class=\"alignnone wp-image-12660\" src=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img7.png\" alt=\"\" width=\"518\" height=\"214\" srcset=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img7.png 740w, https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img7-300x124.png 300w\" sizes=\"(max-width: 518px) 100vw, 518px\" \/><\/a><\/p>\n<p>(b) that the sides don\u2019t &#8220;cross&#8221;

either one could be much larger than the other.\u00a0 It&#8217;s good to visualize two versions, one with each of the sides exaggeratedly longer than the other:<\/p>\n<p><a href=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img9.png\"><img decoding=\"async\" class=\"alignnone size-full wp-image-12662\" src=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img9.png\" alt=\"\" width=\"587\" height=\"295\" srcset=\"https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img9.png 587w, https:\/\/magoosh.com\/gre\/files\/2013\/01\/gga_img9-300x150.png 300w\" sizes=\"(max-width: 587px) 100vw, 587px\" \/><\/a><\/p>\n<p>In the version on the left (AD &gt; AB), it&#8217;s clear that AC\/AB is much much bigger than 1, may be equal to 5 or 6, while AB\/AD is small, only say about 1\/5.\u00a0 In that version, column A definitely would be bigger.<\/p>\n<p>Meanwhile, in the version on the right (AB &gt; AD), now AC\/AB is still larger than 1, but here just larger than 1 &#8212; maybe 6\/5 or 7\/6, much less than 2 &#8212; and now AB\/AD is very large, maybe 4 or 5.\u00a0 In this version, column B would be bigger.<\/p>\n<p>Because the diagram can be changed to make either column bigger, we cannot draw any conclusions.\u00a0 Answer = <strong>D<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>2) It&#8217;s true, we know \u2220EGF = 90\u00b0, but we don&#8217;t know whether EG &gt;

that those two are straight lines.\u00a0 This means, the two angles at point E, \u2220CED and \u2220FEG, have to be the angles formed by intersecting lines &#8212;- known in Geometry as &#8220;<strong>vertical angles<\/strong>&#8221; &#8212; and according to a basic theorem, they must be congruent.<\/p>\n<p>Think about it &#8212; D-E-F is a straight line, so \u2220CED + \u2220DEG = 180\u00b0; C-E-G is a straight line, so \u00a0\u2220FEG + \u2220DEG = 180\u00b0.\u00a0\u00a0 Rearranging these two equations, we know that \u2220CED = 180\u00b0 \u2013 \u2220DEG and that \u2220FEG = 180\u00b0 \u2013 \u2220DEG.\u00a0 The right side of those two equation are identical, so that means the left sides must be equal to each other &#8212;
