twinmonkeytattoo: “ Platonic Solid In three-dimensional space, a Platonic solid is a regular, convex polyhedron. It is constructed by congruent regular polygonal faces with the same number of faces meeting at each vertex. Five solids meet those.
This is a 45 page Smartboard file explaining how the polygon angle sum theorem works. In the lesson is an explanation between regular and irregular polygons, convex and concave polygons, and the names of the most commonly used polygons. Students then learn how to find the total amount of degrees in polygons using the formula and how to find the measurement of just one angle in a regular polygon.
This presentation covers polygons, non polygon (convex, concave). It also lists slides with examples and definitions of the well know types of polygons and their properties. There are also slides that cover special case quadrilaterals. Great for a mini lesson or definition review.
This is a guided, color-coded notebook page for the interactive math notebook on Congruent Triangles and Proving Triangles Congruent using two-column proofs. Includes color-coded two-column proof examples.
