  1. 10.1 Areas of Parallelograms and Triangles By Brit Caswell

  2. Thm 10.1 Area of a Rectangle The area of a rectangle is the product of its base and height. A=bh h b If we know the area of the shape, as well as the base, how do we find the height?

  3. Thm 10.2 Area of a parallelogram The area of a parallelogram is the product of a base and the corresponding height. A=bh h b

  4. Thm10.3 Area of a triangle The area of a triangle is half the product of a base and the corresponding height. A=(1/2)bh h b

  5. Pg 619, #10 Find the area of the parallelogram.

  6. Pg 619, #11 Find the value of h.

  7. Pg 619, #16 Find the area of the triangle.

  8. Pg 620, #17, Think-Pair-Share
