Area of equilateral triangle. In an equilateral triangle ABC, the side BC is trisected at D. Then AD^2 is equal to. In a equilateral triangle, all sides are equal. Since all the sides are of equal length, the side that is the hypotenuse of the right triangle has a length 2x. Answers: 2 Show answers Another question on Mathematics. XY is parallel to BC, XP is parallel to AC and YQ is parallel to AB. Now, the side of the original equilateral triangle (lets call it "a") is the hypotenuse of the 30-60-90 triangle. What is the altitude of an equilateral triangle whose side is 12cm? What is the perimeter of the equilateral triangle? An equilateral triangle is a triangle in which all three sides are equal. 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. Teacher: surendra khileryClass: Maths Language: HindiMedium: Hindi Medium Chapter Name: Video Topics:#maths#mathematics Concept Notes & Videos 260. See the answer. Here are the formulas for area, altitude, perimeter, and semi-perimeter of an equilateral triangle. The in-radius of an equilateral traingle is of length 3 cm. An equilateral triangle is also equiangular that is, all three internal angles are also congruent to each other and are each 60°. The base of a right prism is a right angled triangle. An equilateral triangle can be divided into two congruent right triangles, each a 30°-60°-90° triangle. Let ABC be the equilateral triangle with AD as an altitude from A meeting BC at D. Then, D will be the midpoint of BC. Lets assume a, b, c are the sudes of triangle. Notice that that 6 is the value of "s", across from the 30 degree angle at the top. The internal angles of the equilateral triangle are also the same, that is, 60 degrees. 1. Find the height of an equilateral triangle of side 12 cm. 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 Area of a triangle = 1/2 * b * h Let the sides of the equilateral triangle be 2x and form a right-angled triangle by drawing a vertical line down the middle. An equilateral triangle with side length 12 cm is shown in the diagram, work out the height of the triangle. The decimal answer is an estimate. Geometry. A second side of the triangle is 6.9 cm long.
