Question

How to find the altitude of an equilateral triangle if the side of length is given?

Answer 1

Explanation:

The main application use of altitude is that it is used for area calculation of the triangle, i.e. area of a triangle is (½ base × height). ...

For an obtuse-angled triangle, the altitude is outside the triangle. ...

Therefore, the Altitude (Height) of an equilateral triangle = h = (√3/2) × s.

Answer 2

The main application use of altitude is that it is used for area calculation of the triangle, i.e. area of a triangle is (½ base × height). ...
For an obtuse-angled triangle, the altitude is outside the triangle. ...
Therefore, the Altitude (Height) of an equilateral triangle = h = (√3/2) × s.
