VISUALIZATION
Essential Question: How can you represent a threedimensional figure with a twodimensional drawing?
 Students will make nets for solid figures
 Isometric and orthographic drawings will be used to show attributes of figures
Essential Question: What are the building blocks of geometry?
 Students will design basic geometric figures
 Undefined terms such as point, line, and plane will be shown with visual representations
 Postulates, which will lead to proofs, will be presented
Essential Question: How can you describe the attributes of a segment or an angle?
 Segments will be measured with and without a coordinate grid
 Students will use the midpoint and distance formulas
 Protractors ("bleechh! how pedestrian?!"  Mr. C.) will be used to measure angles
