1-4.
Decide what the shapes below have in common. Write your answer in a complete sentence. Then draw two more shapes that belong to the same set.
Note: Many answers are possible.
Look for something true about all the shapes.
Consider things like:
-How many sides do they have?
-What types of angles do they all have?
-What names could describe all of them?
They all have at least one obtuse angle; they are all polygons.
Now, draw two more shapes that would belong to the set of shapes above.
