2020年1月2日 · Equilateral triangle: A triangle with equal angle and equal sides. The sum of an angle in a triangle is 18 0 o this implies that each angles have 6 0 o. The area rule of triangle: It states that the area of any triangle is equal to half the product of the lengths of the two sides of the triangle, multiplied by the sine of the angle.
Equilateral Triangle: Definition, Properties, Formulas - Math Monks
2023年8月3日 · Equilateral triangle is a figure where all three sides and angles are equal. 1. All three sides are equal; in ∆ABC, sides AB = BC = CA. 2. All three angles are equal (equiangular), so ∠ABC = ∠BAC = ∠ACB = 60°. 3. There are three lines of symmetry. 4.
Equilateral triangle - Wikipedia
An equilateral triangle is a triangle in which all three sides have the same length, and all three angles are equal. Because of these properties, the equilateral triangle is a regular polygon, occasionally known as the regular triangle. It is the special case of an isosceles triangle by modern definition, creating more special properties.
