The base of a solid oblique pyramid is an equilateral triangle with a base edge length of 18 inches.What is the height of the triangular base of the pyramid?

Answers

The task is, in fact, to find the height of the equilateral triangle with a base edge ob 18 inches. Let ΔABC be the base with AB=BC=CA=18 in. Let AD be an altitude perpendicular to the side BC. Consider the triangle ADB, it is right triangle with hypotenuse AB=18 in., leg DB=18÷2=9 in. and AD unknown leg. By the Pythagorean theorem: Answer: the height of the triangular base of the pyramid is .
