| Prove: |
|
(HINT: Use Heron’s Formula.)
To Prove:
Area of the equilateral triangle
Proof:
Let’s consider a
If the three sides of a triangle have lengths
where the semiperimeter of the triangle is
As all sides are of equal length
Substituting the above values in the semiperimeter formula,
Applying the Heron’s formula for
