The light blue polygons are features in layer A. The darker blue are in layer B.

1. Draw a convex hull around the features in layer A.
2. How many features will result from the union of A and B? Label them with numbers.
3. How many features will result from the intersection of A and B?
4. If A is the clip layer and B the input layer, what is the result?
5. If B is the clip layer and A the input layer, what is the result?
6. What does the symmetrical difference of A and B look like?
7. What does A as input layer and B as difference layer produce?
