A couple of weeks ago, in my Tech Math class, we were asked to find the areas of various triangles. No problem, any student worth their salt in geometry skills knows that the area of a triangle is one half times the length of the base times the height.
For one of the problems given, we had a scalene triangle with only the length of the sides of the triangle listed on the page. After much confusion by the whole class, Mr. Nichols told us in the next session that we needed a formula that we were not given before, Heron’s Formula. An excellent white paper exists to explain this, but I will try to condense that after I understand it myself. I just do not have time to read it at the moment.
