1. Cut along sides the dotted lines and the solid lines (i.e. the edges of the polygon).

Now, you have a polygon and pieces of exterior angles from the polygon.

2. Polygon: Follow the instructions inside the polyon and fill in the blanks.

3. Exterior angles: Place all the pointed ends (i.e. exterior angles) adjacent to each other. Paste them together. What do you notice?

4. Paste these two pieces of work side by side in your notebook.

Submission of work in padlet.

5. Post a photo comprising the cut-outs, both the polygon and exterior angles.

6. Key in your observation in Step 3 (above).
