Are these really parallelograms?
Continuing with the idea in my post about Squares that aren't squares?, let's look at the following "parallelograms".
The question is the same:
Does the given information in each diagram guarantee that each is a parallelogram?
If you don't think so, your mission is to draw a quadrilateral with the given information but that clearly does NOT look like a parallelogram.
Figure 1:
Figure 2:
Figure 3:
Figure 4:
Again, these problems let students practice logical reasoning, and also learn about parallelograms, of course. See answers here.
