Geometry: Chapter 6- polygons, parallelograms, rectangles.
Students use decomposition to identify a triangle and move it to create a rectangle with the same base and height as the parallelogram. After looking at several examples of different parallelograms, students should be able to generalize to the formula (MP.7 and MP.8).

Classify polygons according to their attributes, like number of sides and angles, and justify this classification (MP.2, MP.3, MP.5). Understand that a polygon is a closed shape with straight sides. (Optional) Understand that a regular polygon is a polygon with sides of equal length.; Understand that a triangle is a polygon with three sides and three angles.
So, the area is 7 times 3, or 21 square inches. This is the same area formula as with squares and rectangles. And, if you remember, squares and rectangles also have sets of parallel sides, so they.
In This Unit. lesson 1: The Area of Parallelograms Through Rectangle Facts lesson 2: The Area of Right Triangles lesson 3: The Area of Acute Triangles Using Height and Base lesson 4: The Area of All Triangles Using Height and Base lesson 5: The Area of Polygons Through Composition and Decomposition lesson 6: Area in the Real World.
A polygon is a shape that has no curves. In this unit, we will focus on quadrilaterals, which are polygons with four sides. While each has their own set of characteristics, they share some properties with other quadrilaterals. Completing this unit should take you approximately 4 hours.
