The ideas in this geometry lesson are taken from the Geometry ebook that I sell at MathMammoth.com. This lesson plan does not contain all the problems the Geometry ebook does. Parallel and perpendicular lines

2. a) Draw a parallelogram that has a 50 angle. You can decide the length of the sides of the parallelogram. What else do you need to know to be able to draw the parallelogram?
b) Draw a parallelogram that has a 118 angle.
5. Find one corresponding angle to each of the marked angles and mark
them the same way.
