Answer:
When the perimeter is given: It is obvious that an equilateral triangle's perimeter is three times the length of its side; hence, dividing the perimeter by three would result in the length of the triangle's side. Therefore, the length of a side in an equilateral triangle is equal to one-third of the triangle's perimeter.
Step-by-step explanation:
Step : 1 Since a triangle's side is always positive, it follows that AP=423 AP = 4 2 3 from the derived equation. As a result, a square of 2 units may contain the greatest equilateral triangle of 423 units (4 2 3 units). K = (1/4) Area of Equilateral Triangle * √3 * a2. Equilateral Triangle Altitude Formula: h = (1/2) * 3 * a Equilateral triangle's angles are A = B = C = 60 degrees.
Step : 2 To ascertain the missing side lengths of an equilateral triangle, utilise the Pythagorean theorem and the height of the right triangles included within the equilateral. After that, you may calculate the area of an equilateral triangle using the formula A = 3/4 (a2). The lines of symmetry of an equilateral triangle are its median, angle bisector, and altitude, which are all the same for each side. An equilateral triangle has an area of 3 a2 4. An equilateral triangle's perimeter is 3a.
