Equilateral Triangle. Three equal sides Three equal angles, always 60 ... The perimeter is the distance around the edge of the triangle: just add up the three sides:
Properties of Equilateral Triangle. All three sides are equal. All three angles are congruent and are equal to 60 degrees. It is a regular polygon with three sides. The perpendicular drawn from vertex of the equilateral triangle to the opposite side bisects it into equal halves.

- A triangle that has all its sides equal in dimension and each angle measure up to 60 degrees, is called an equilateral triangle.
- The formula to find area of equilateral triangle is given by: A = (√3/4)a2, where a is the length of side of equilateral triangle.
- The perimeter of an equilateral triangle is the sum of all its three equal sides. Perimeter = 3a, where a is the length of its sides.
- The formula to find the height of equilateral triangle is: Height, h = (√3/2)a, where a is the side of the equilateral triangle.
- An equilateral triangle is a regular polygon or a regular triangle.
- Based on sides, there are three different kinds of triangles. Their names are: Scalene triangle Isosceles triangle Equilateral triangle
- All triangles have 3 sides only.
- Perimeter = 3 x sides of equilateral triangle Perimeter = 3 x 10 = 30 cms
We know that a triangle is a three-sided polygon that consists of three edges and three vertices. There are three types of triangle based on the length of its sides: Equilateral triangle: All sides are equal in length. Isosceles triangle: Two sides are equal in length. Scalene triangle: All sides have different lengths.
Below given is a triangle having three sides and three edges, which are numbered as 0,1,2. Definition. As we discussed in the introduction, a triangle is a type of polygon, which has three sides, and the two sides are joined e nd to end is called the vertex of the triangle. An angle is formed between two sides.

Vertices of a Triangle. Triangle is a three-sided 2D shape or polygon. A triangle is made up of three line segments or sides. A triangle has 3 sides, 3 vertices and 3 angles. A triangle is denoted by the symbol $\Delta$ . In $\Delta$ ABC, (AB, BC), (BC, CA) and (CA, AB) are adjacent sides of the given triangle. “A”, “B”, “C” are the ...
Triangles have many types based on the length of the sides and the angles. A triangle whose sides are all the same length is an equilateral triangle, [3] a triangle with two sides having the same length is an isosceles triangle, [4] [a] and a triangle with three different-length sides is a scalene triangle.

The third figure has a curved side. Parts of a Triangle. A triangle has 3 sides. In triangle ABC, the sides are AB, BC, and CA. The angle formed by any two sides of a triangle is the angle of the triangle, denoted by the symbol ∠. A triangle has three angles. The three angles of the triangle ABC are ∠ABC, ∠BCA, and ∠CAB.
