What is a parallelogram? The definition says it's a figure enclosed by two sets of parallel lines, and that's where we will start. The DEFINITION does not say a thing about its side lengths or angle measures. Those things students can notice or find out for themselves by drawing and measuring.
I also draw a bigger copy of a given rhombus, which is a very good drawing exercises for students, and give ideas for more drawing problems on a basic level.
