Geometry terms
You are to create a glossary of the following terms. This project is worth 100 points (total) and will count as
homework grades. The points will be determined as follows: 30 points for Part I, 35 points for Part II and 35 points
for Part III. The terms should be in the order given on this page. For each term, find the most accurate and complete
definition you can, and include a diagram to strengthen the definition. Correct spelling and grammar is expected. A
‘Works Cited’ page for the sources of definitions and ‘cut and paste” diagrams are required. The project should be
neat and organized. Due dates are on the assignments page.
