Calculating The Area Of A Triangle Math

The base refers to any side of the triangle where the height is represented by the length of the line segment drawn from the vertex opposite the base to a point on the base that forms a perpendicular. The perimeter is the sum of the three sides of the triangle and the area can be determined using the following equation. The best known and the simplest formula which almost everybody remembers from school is.
