This is a 2-page document that shows the diagonals in regular polygons (square, pentagon, hexagon, septagon, octagon, nonagon, decagon and dodecagon). The first page has the diagonals drawn in, with the number and characteristics. The second page has the shapes with no diagonals or information on it. Students can draw the diagonals. These sheets go directly with my powerpoint "Regular Polygons and Diagonals." This powerpoint begins with the definition of a diagonal and goes step-by-step through the process of drawing, counting and discovering the characteristics of diagonals in each of the shapes. By doing this activity, students discover for themselves the important things they need to know about diagonals of regular polygons. It is a detailed powerpoint and explanation which has been very effective with my students.
