Topic 3 Homework
1. Sketch and clearly label the black and red tile arrays and edge sets determined
by the following collections:
a. Collection A: Edge I—1B and 1R tile, Edge II—3B and 1R tile
b. Collection B: Edge I—2B and 1R tile, Edge II—1R tile
2. For each of the following arrays, sketch and clearly label the minimal array
whose edges have the same net values as the edges of the arrays shown.
Show the steps changing the original collection to the minimal collection.
a. Collection A: Edge I—1B and 2R tiles, Edge II—1B and 3R tiles
b. Collection B: Edge I—3B and 1R tiles, Edge II—2B and 1R tiles
3. For the following integers, sketch and clearly label all of the possible minimal
arrays with this net value. Include clearly labeled edge sets.
a. NV = 4
b. NV = -9
4. Sketch and clearly label two different arrays with net value zero. Include clearly
labeled edge sets.
