The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent.
To use the Pythagorean theorem, we need to find the slant length and the distance from the center of the square base to the middle of the triangular side. Since the base is a square of 144 sq. units, the length of each of it's sides is the square root of 144 which is 12. So each of the fours sides of the square base is 12 units long. The distance from the center of the square base to one of the sides is 1/2*12 or 6 units long. The area of one of the triangle sides is 1/2*base length * slant height. We know the area is 72 square units and the base length is just one side of the square base or 12 units. So we have this equation: 72=1/2*12*slant height simplifying 72=6*slant height rearranging 72/6= slant height 12= slant height.
