[TowerTalk] height of equilateral triangle?

[Jim Rhodes]

Wh as t you really want to know is the height of the right triangle that is
half of your equilateral triangle. So square the length of one side, then
square half of one side. Subtract the smaller result from the larger, then
take the square root of v the diffrrence. That is the height.
