1. Using the segment tool[icon]/images/ggb/toolbar/mode_segment.png[/icon] on the open Geogebra window below, construct a non-regular polygon with either 5, 6 or 7 sides (your choice).[br]2. Label the vertices using the text tool. [icon]/images/ggb/toolbar/mode_text.png[/icon][br]3. Construct one set of exterior angles using the ray tool[icon]/images/ggb/toolbar/mode_ray.png[/icon]. Make sure your exterior angles all go the same way, like the picture below.
4. Measure the exterior angles. Make sure to measure the exterior angles less than 180.
What is the sum of the exterior angles?
What is the sum of the exterior angles now?
Complete the following conjecture: The sum of the exterior angles of any polygon is ___________
