\n" ); document.write( "\n" ); document.write( "If you divide the perimeter of an equilateral triangle by 3, you will get the measure of one side. If you construct an altitude in the triangle, you will make a 30-60-90 right triangle where one side of the equilateral triangle is the hypotenuse of the right triangle and the short leg is one-half of a side of the equilateral triangle. Since the sides of a 30-60-90 triangle are in proportion:\r
