Geometry Area Of Square Inscribed In A Triangle Gre Gmat Cat Sat Defg (shaded) is a square inscribed in Δabc. ap is the altitude of the triangle. if ap=4, bp=5 and pc=3 what is the area of square defg? a) 125 16b) 64 9c). The logic you applied is perfectly valid ( only if you take that rectangle to be a square. i.e. the angle you took 45 degree in 2rsin45 and 2rcos45 is only valid if that rectangle is a square). to illustrate the above, draw two rectangles with the same area 100.
Area Of Square Inscribed In A Triangle R Gre 1. answer c. use tan60 to get side of triangle if you are assuming square side to be x. so side of equi. triangle is. x 2*x tan60. now ratio of area=area of square (side x) area of triangle (x 2*x tan60).after calculation and rationalisation we will get ans.c. posted from my mobile device. lacktutor. If given the area of the square, we should be able to derive essentially any other information. area of an equilateral triangle. the area of an equilateral triangle equals (s²√3) 4. memorize this. it will save you the time of drawing a 30 60 90 triangle, solving for the base, finding the height, multiplying and dividing by 2. Understanding the word inscribed. figure 1: a triangle inscribed inside of a circle. the textbook definition of inscribe is as follows: to draw or delineate (one figure) within another figure so that the inner lies entirely within the boundary of the other, touching it at as many points as possible. describes it as one shape. To find the area of a rectangle, multiply the length by the width. for a square, multiply the side length by itself. diagonals are often part of gre problems, and you can use the pythagorean theorem to find diagonal lengths in rectangles and squares. these formulas are crucial for solving questions about area, perimeter, and diagonals.

Area of a circle = πr 2. π(2√2) 2; π(2 2)(√2 2) π(4)(2) 8π; thus, (c) is correct. look out for hidden triangles in sat geometry questions. if you get a question with a square inscribed in a circle, remember that the diagonal of the square doubles as the hypotenuse of a a 45° 45° 90° triangle. Consider a,b as right legs and c as the hypotenuse. let side of square = s ac = b, bc = a, ab = c. fb = as b and ae = bs a as the colored triangles are similar to the bigger triangle. steps to calculate area (s^2) : 1)calculate gb and ad using right angle triangle rule for triangles gbf and ade. 2)calculate gd using right angle triangle rule.
