**Steve**, Tuesday, August 20, 2013 at 12:38pmWouldn't be easier just to post the problem as stated? The language above is gibberish. How about

show that the altitudes of an equilateral triangle are √3/2 of a side

Draw the altitude.

Now you have a right triangle, with legs h, s/2 and hypotenuse s.

Using the Pythagorean Theorem,

h^2 + (s/2)^2 = s^2

h^2 + s^2/4 = s^2

h^2 = 3/4 s^2

h = √3/2 s
