This power point presentation discusses the area of triangles. It states that the area of any triangle inscribed within a quadrilateral is equal to half the base multiplied by the height. It provides examples of triangles inscribed within a quadrilateral ABCD and demonstrates that their areas are equal to half of AB multiplied by the distance between A and C. It asks what if there is no quadrilateral and provides examples of determining the area of triangles using bases and heights without an enclosing shape.
