GoalConstruct polygons based on angle measures and side lengths.
Builds UponStudent Book pages 218220 Instructions for UsePolygons allows students to measure the angles of polygons using an interactive protractor. To use Polygons, click in the protractor button to pop up the protractor on the screen. To move the protractor or rotate it on the screen, grab the small circle on the protractor and drag it. Set the number of sides for the polygon using the up and down arrows on the number button. Click the number button, to pop up a polygon. Click the up or down arrows of the yellowtriangle button to increase or decrease the size of the polygon. To measure the polygon, grab the protractor and move it over the polygon. Place the center base of the protractor on any point on the polygon. Align the base of the protractor with the side length of the polygon. Measure the angle of the polygon. Move the protractor to another length of the polygon and measure another angle. Click on any points of the polygon to change its shape. Click the 'Reset' button to start again. Click the 'Quit' button to exit the program.
Polygon Angle Applet allows students to identify and classify regular polygons. To use Polygon Angle Applet , scroll down to find the applet. Input the number of sides of a regular polygon and click the 'Solve' button. The name of the polygon, the sum of the measure of the interior angles, the measure of each interior angle, and the measure of each exterior angle will appear.
