This structured inquiry lesson uses a discovery approach to explore the how to the area of a right triangle by using the formula for finding area of a triangle.
Students will gain a stronger understanding of finding the area of a right triangle. They will view a triangle as part of a parallelogram composed of two copies of that triangle, and compose triangles into rectangles, as well as decompose rectangles into triangles to determine their areas. In addition, they will justify and find relationships among the formulas for the areas of different polygons.
