Use this simplified tool bar to create simple geometric figures.

1.) Create regular triangle[br] a) click on the regular polygon tab [br] b) label two random points (A and B) [br] c) when prompted enter 3 for the vertices [br]2.) Calculate the sum of the interior angles: Formula=(n-2)*180[br]3.) Calculate each angle for a regular polygon: Formula= (n-2)*180 / n[br]4.) Use the applet to check your answer [br] a) click on the angle tab[br] b) click on segment: AB & AC, CA & CB, and BA & BC[br] c) compare your results[br]  [br]  *Answer: Sum of the interior =180, Each angle=60[br][br]5.) Repeat the process creating a polygon with 5,6, and 9 vertices [br]6.) Calculate the sum of the interior and each angle using the formulas [br]7.) Use the applet to check your results
