**Marth**, Friday, January 15, 2010 at 5:15pmThe triangle is isoceles, so there will be 1 base and 2 sides of equal length. A perpendicular line segment from the base to the vertex of the other 2 sides (aka the height) will also be the midpoint of the base. You then have a right triangle, with the hypotenuse being the side length, and the base being 1/2 the base of the isoceles triangle.
