1. ## Triangle

Where does the square root 3 come from. I get the height to s^2 = H^2 + (s/2)^2 ==>

H = s/2 ==> A = B * H (B = s ) so (S*S)/(2 * 2) ==> A = s^2 / 4 ,,,where do i
get the square root 3.

2. Being able to see the triangle would be nice...

3. All sides are equal,,they are all s

4. I just want to know where the square root 3 comes from in the formula,, the formula is for calculating the Area of a trinagle where all sides are the same lenght.

remember the relationships betwen the sides of a 30-60-90 triangle?

get the square root 3.

Of course, if you'd bothered to do as suggested, and make use of Heron's Formula, the appearance of $\displaystyle \sqrt{3}$ is obvious...
