Question

explain equilateral triangle​

Answer 1

Answer:

In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°. 

Area: (√3/ 4 ) x (side of equilateral triangle)²

Perimeter: 3 x side of equilateral triangle

Number of vertices: 3

Number of edges: 3

Internal angle: 60°

An equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60.

Some formulas of Equilateral triangle =

• Area = $\frac{ \sqrt{ 3} }{4} \times {side}^{2}$
• Perimeter = 3× side
