An equilateral triangle has all three sides equal and all three interior angles equal too. In the example below a 8 metres. For a triangle that has 3 equal sides the semi-perimeter is simply s 3a 2.
We will first look at finding the area of an equilateral triangle using Herons formula. That is all three internal angles are also congruent to each other and are each 60. A triangle with all sides equal is called an equilateral triangle and a triangle with no sides equal is called a scalene triangle.
Use the calculator on below to calculate the area of a triangle given 3 sides using Herons formula. All triangles have three sides and three angles but they come in many different shapes and sizes. Enter the length of any two sides and leave the side to be calculated blank.
It is also a regular polygon so it is also referred to as a regular triangle. Can a acute triangle be a right triangle. No matter how you position the three sides of the triangle the total degrees of all interior angles the three angles inside the triangle is always 180.
In this case each interior angle of an equilateral triangle is 60 degrees. If this is true for all three combinations of added side lengths then you will have a triangle. ENTER THREE SIDE LENGTHS.
