Refer to polygon ABCDEF and complete the following activity, then answer the first four questions. One diagonal is drawn from points F to C. Add more diagonals that do not overlap; in other words, the lines do not cross each other. Copy the figure or print it to paper to draw all possible non-overlapping diagonals. |
|
|
| |
1) Using two letters for each segment, name the other diagonals that you drew. |

Print out or sketch the table shown below. Complete each part of the table. Use the polygons that are below the table to determine the number of triangles that can be drawn using non-overlapping diagonals to connect the vertices in each polygon. After completing the table, answer the next four questions. |
