2/19 Applied Geometry - Developing Formulas for Area of Triangles and Parallelograms

Today we will be working with the area formulas for triangles and parallelograms. The students should already be familiar with the formulas, we will be explaining where they come from today. In addition to the easier calculation problems, students will also be doing some algebra to find the parts of a figure when the area is known or when the perimeter is known. There will also be some areas that include variables as will as numbers. Seen above is an SAT/ACT math problem involving the area of a triangle that deals with more than just calculating the area based on the formula. Our homework problems are not quite this involved, but they are along the same lines.
