10.1 Areas of Parallelograms and Triangles By Brit Caswell

A=bh 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?

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

A=(1/2)bh Thm 10.3 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
