Similar Triangles And Proportions Ged Math Possible answers: correct answer: explanation: corresponding angles of similar triangles are congruent, so, since is right, so is . this makes and the legs of a right triangle, so its area is half their product. by the pythagorean theorem, since is the hypotenuse of a right triangle with legs 6 and 8, its measure is. . The ged’s math test is a single section composed of forty six problems; 115 minutes are allotted for it, giving you two and a half minutes to solve each problem. the on screen calculator is not available to be used while answering the first five questions; after completing these, the calculator can be used for the remaining forty one questions.
Similar Triangles And Proportions Ged Math Properties of similar triangles are given below, similar triangles have the same shape but different sizes. in similar triangles, corresponding angles are equal. corresponding sides of similar triangles are in the same ratio. the ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides. This proportionality of corresponding sides can be used to find the length of a side of a figure, given a similar figure for which sufficient measurements are known. in the displayed triangles, the lengths of the sides are given by a = 48 mm, b = 81 mm, c = 68 mm, and a = 21 mm. find the lengths of sides b and c, rounded to the nearest whole. 42in. correct answer: 51in. explanation: to find the perimeter of a triangle, we will use the following formula: p = a b c. where a, b, and c are the lengths of the sides of the triangle. now, we know one side of the triangle has a length of 17in. because it is an equilateral triangle, all sides are equal. 2) since the triangles are similar, we can use proportions ratios to find the other coordinate (and lengths). bc ac 2x — x cd ce since c is at ( 1, 2), a horizontal move 20 units to the fight to point e 40 20 3) using the pythagorean theorem, 4 25 4 29 * *since the ratio of the triangles is 1:4, the length of ae should be 4 29.
