We cant have the answers for they need a handout so maybe put the answers on a sheet of paper or something or you could just print it after we make the parallelogram samples and then we add the answers in so they don't have them but the slide still does

I will add text boxes for the questions.
Max Rauchenberger
lol, we could just work out the problems on the board ;)
Timothy Murzanski
I'll make the notes page

Theorem 100The area of a parallelogram is equal to the product of the base and the height.

A = bhwhere “b” is the length of the base and “h” is the height

Page 3: Lesson 11.2 Area of Parallelograms and Triangles

Theorem 101The area of a triangle is equal to one half the product of the base and the

height (or altitude) for that base.A = ½(b x h)

where b is the length of the base and h is the altitude
