We all know that a triangle is a polygon, which has three sides. The area of a triangle is a measurement of the area covered by the triangle. We can express the area of a triangle in the square units. The area of a triangle is determined by two formulas i.e. the base multiplies b...
The base and height method is the most commonly used and taught method to find the area of a triangle. Any side can be the base of the triangle, and the height, or altitude, is the perpendicular length from the base to its opposing vertex. Given the base and height, the formula to...
