Equilateral Triangle. In geometry, an equilateral triangle is a triangle that has all its sides equal in length. Since the three sides are equal therefore the three angles, opposite to the equal sides, are equal in measure. Therefore, it is also called an equiangular triangle, where each angle measure 60 degrees.

Area = √3/4 × (side)2. In the given triangle ABC, Area of ΔABC = (√3/4) × (side) 2, where, AB = BC = CA = a units. Thus, the formula for the area of the above equilateral triangle can be written as: Area of equilateral triangle ΔABC = (√3/4) × a 2. Example: How to find the area of an equilateral triangle with one side of 4 units? Solution:
Equilateral triangle is a triangle in which all sides are equal and angles are also equal. The value of each angle of an equilateral triangle is 60 degrees. Learn more about the equilateral triangle, properties, formulas along with solved examples.
An equilateral triangle is the one in which all sides of the triangle are equal and have equal angles measures. Equilateral triangle formulas are used to calculate the area, altitude, perimeter, and semi-perimeter of an equilateral triangle.
Aug 3, 2023 · Definition. Equilateral triangle is a figure where all three sides and angles are equal. Equilateral Triangle. Properties of an Equilateral Triangle. 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 formulas: area, perimeter, base, height, side. Drawing, definitions and properties.
An equilateral triangle is a triangle whose three sides all have the same length. They are the only regular polygon with three sides, and appear in a variety of contexts, in both basic geometry and more advanced topics such as complex number geometry and geometric inequalities. Identification. Basic Properties.
An equilateral triangle is also called an equiangular triangle since its three angles are equal to 60°. In an isosceles triangle, the base angles are congruent. Recall from above that an equilateral triangle is also an isosceles triangle. Since DE≅EF, the base angles, ∠D and ∠F, are congruent.
Jul 19, 2024 · An equilateral triangle is a triangle with all three sides of equal length a, corresponding to what could also be known as a "regular" triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal.
