Find the height of an equilateral triangle with sides of 12 units. Therefore, BD = 1/2 x BC = 6 cm, Now, In ∆ADB, using Pythagoras theorem, we have, (Perpendicular)2 + (Base)2 = (Hypotenuse)2, Hence, the height of an equilateral triangle is 6√3 cm.

Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. Find the Height of an Equilateral Triangle Having Side 2a. An equilateral triangle with side length 12 cm is shown in the diagram, work out the height of the triangle. To find the height, we can draw an altitude to one of the sides in order to split the triangle into two equal 30-60-90 triangles. Find the length of the side and perimeter of an equilateral triangle whose height is $\sqrt{3}$ cm. To find the height we divide the triangle into two special 30 - 60 - 90 right triangles by drawing a line from one corner to the center of the opposite side. That means the bottom side of 12 cm is split into 6 cm on the left and 6 cm on the right. What is the perimeter of the equilateral triangle? Find its distance from third side. Equilateral triangles have sides of equal length, with angles of 60°. Find the perpendicular height of an equilateral triangle whose side is 12 cm - 32791679 In a equilateral triangle, all sides are equal. The height of the triangle is: h = 12 cm h = 12 c m Let the side of the triangle be x x. It consists of three angles whose sum is equal to 180 degrees. Geometry. An equilateral triangle has a height of 26 inches. The height of an equilateral triangle having each side 12cm, is (a) 6√2 cm (b) 6√3m (c) 3√6m (d) 6√6m, The lengths of the diagonals of a rhombus are 24cm and 10cm. A.24 cm^2 B.36 cm^2 C.24√3 cm^2 D.36√3 cm^2 E.40√2 cm^2 When all sides and all angles are equal then the triangle is said to be an equilateral triangle. Mathematics, 21.06.2019 17:20. Leslie G. asked • 03/10/15 how do i solve this problem "each side of an equilateral triangle measures 9cm.Find the height ,h,of the triangle A second side of the triangle is 6.9 cm long. The internal angles of the equilateral triangle are also the same, that is, 60 degrees. The decimal answer is an estimate. The in-radius of an equilateral traingle is of length 3 cm. Here are the formulas for area, altitude, perimeter, and semi-perimeter of an equilateral triangle. Important Solutions 1578. An equilateral triangle is a triangle in which all three sides are equal. Find the height of an equilateral triangle of side 12 cm. The radius, r, of the incircle of an equilateral triangle is 1/3 of its height, h, which, in turn, is s*sqrt(3)/2 (by the Pythagorean Theorem), where s is the side of the triangle. Since all the sides are of equal length, the side that is the hypotenuse of the right triangle has a length 2x. Find the area of an equilateral triangle whose side is 12 cm,find the altitude of the triangle - 3294172
