Question 702431
<font face="Times New Roman" size="+2">


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:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{1}{2}:\frac{\sqrt{3}}{2}:1]


you need to multiply the measure of the side of the equilateral triangle times *[tex \LARGE \frac{\sqrt{3}}{2}] to get the altitude of the equilateral triangle.
