Objectives: Students will be able to • Construct, measure and manipulate two-dimensional objects using The Geometer`s Sketchpad. • Classify and construct regular polygons based upon information regarding angle and/or side measure. • Measure a pentagon, then a hexagon, and determine without performing the construction, how many degrees are in the interior of a 21-sided figure. • Identify similar figures and use their properties.
