Calculating Area of Equilateral Triangle
|
|
|
|
|
An equilateral triangle is the one which has three equal sides and is a regular polygon, in this case with three sides. It also has three equal angles and therefore can be also termed as an equiangular triangle. All the facts and properties described for regular polygons apply to an equilateral triangle.
Properties:
All three angles of an equilateral triangle are always 60°.
Since the angles are the same and the internal angles of any triangle always add to 180°, each is 60°.
It is possible to construct an equilateral triangle of a given side length using just a compass and straightedge |
