Which of the following statements best explains why the algebraic formula for the area of a triangle is 1/2bh
A. A parallelogram can be transformed into a rectangle if a triangular piece is moved from one side to the other.
B. The height of a triangle is not equal to the length of one of its sides, and the length must be divided by 2 to be used to find the area of the triangle.
C. A parallelogram is composed of two congruent triangles, so the area of a parallelogram with the same base and height as the triangle can be divided by 2 to find the area of the triangle.
D. This formula is only true for scalene triangles because all of their sides are different lengths, so one has to use the base and height to find the area.
Answer: C. A parallelogram is composed of two congruent triangles, so the area of a parallelogram with the same base and height as the triangle can be divided by 2 to find the area of the triangle.
