The Sum of the Interior Angles of a Polygon
Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this lesson.

Complementary and Supplementary Angles: Geometry "Nspired"
Learners investigate complementary and supplementary angles. They use dynamic geometry (TI-nspire) software to manipulate rays to identify the conditions necessary to create complementary and supplementary angles. They find the measure...

Polygons-Changing Area Versus Changing Perimeter
Investigate the area and perimeter of polygons in this geometry lesson. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape of...
