  1. Learning Targets: We will learn to find the perimeter and area of different parallelograms We will learn to determine whether (x, y) points form a parallelogram Review: 11.1 Areas of Parallelograms

  2. Geometry Activity* You Have 2 Parallelograms (Only Cut One and put the Other Aside) • To find the area formula of a parallelogram, cut one of your parallelograms and then arrange the two pieces to form a rectangle (think before you cut) • Label your length and width on your rectangle • Go back to your original parallelogram and label segments that are equal to the length and width of the rectangle.

  3. Ex 1: Perimeter and Area of a Parallelogram We can have different parallelograms having the same area*

  4. Example 2: Real World Application

  5. Example 3*: Area of the x-y Coordinate Plane With a partner write down a plan as to how to find the area of this quadrilateral!
