What is the Base of a Parallelogram?
A base of a parallelogram is any one of its sides. The base and the corresponding altitude are identified based on the side that is chosen as its base. In this activity, you are going to use the applet below to demonstrate the base of a parallelogram. Just follow the steps below.
(1.) What can you say about the areas of parallelograms with the same base and the same height?
(2.) Give a convincing argument that two parallelograms with the same base and the same height have the same area.
Study the parallelograms A and B below carefully.
(1.) Select all the statements that are true about bases and heights in a parallelogram.
