Area of Triangles and Parallelograms

Area of Parallelograms

• To find the area of a parallelogram, multiple the base x the height.

• The height meets the base to form a right angle - the slanted side of the parallelogram is NOT the height (you won't need to use the slanted side at all when finding the area)

Area of Triangles

• To find the area of a triangle, multiply base x height ÷ 2

• The base and height will form a right angle where they meet. Sometime the height will be one of the triangle's sides, sometimes it won't be...

• It will look like a T or an L where the base and height meet.
