10.2 Geogebra Task
- Create a circle with a center, A, through a point, B.
- Construct two chords by creating two lines through the center, creating segment connecting the points of intersection to the circle, then hiding the lines.
- Create four arcs using the "Circular Arc" tool. Select the center then the two endpoints of the arc in a counter-clockwise motion.
- Measure the lengths of the circumference of the circle, the four arcs, and the four central angles created.
- Insert text showing the ratio (decimal rounded to nearest tenth) of the four arcs each to the circumference
- Insert text showing the ratio (decimal rounded to the nearest tenth) of the four central angles to 360.
- If all four decimal match the other four - you are done!
