To determine the area of a triangle, you use the formula: Area = 1/2 × Base × Height. This formula works because a triangle is essentially half of a rectangle or square. By identifying the base (the bottom side) and the height (the perpendicular distance from the base to the opposite vertex), you can calculate the space enclosed by the triangle, which is useful for real-world applications like land measurement and construction. Let's look at some examples! Triangles part 4
