A) We showed how to find the area of a parallelogram using moving/additivity and shearing. Another way to find this formula is by breaking a parallelogram into two appropriate triangles (they have have the same base and height). Trace the parallelogram (or draw a new one) and show how to divide it into two triangles. Then, use the area of a triangle to get the formula for the area of the parallelogram. h b
