How do you calculate the area of a triangle?

To calculate the area of a triangle, the formula used is ( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} ). This formula is derived from the general concept of area, which involves multiplying the base by the height to find the area of a rectangle, and then recognizing that a triangle can be seen as half of a rectangle.

When you use this formula, the base refers to the length of one side of the triangle, while the height is the perpendicular distance from that base to the opposite vertex. By taking half of the product of the base and height, you account for the triangular shape as opposed to that of a rectangle.

This triangle area formula is fundamental in geometry and is essential for solving problems involving triangles. Understanding this concept is crucial for students as it serves as a foundation for more advanced topics in mathematics and geometry.
