Part II Chords and Perpendicular Radii Questions 1-6
1. Use 
(Circle with Center and Radius) to create a 4 unit radius circle with centre A.
2. Use 
(Segment between Two Points) to create a chord, BC.
3. Use 
(Perpendicular Bisector) to bisect the chord, click on the two points of the chord.
4. 
(New Point) Place a point, D, at the bisecting intersection.
5. Use 
(Distance or Length) to measure the length of the line segments created by the bisecting line (BD and CD). Click on the two points to produce a measurement.
6. Repeat this experiment by drawing chord EF and repeating steps 3 to 5.

Repeat this experiment by drawing 2 more circles, one smaller and one larger and drawing 2 chords on each circle, and repeat steps 3 to 5.
Part II Chords and Perpendicular Radii: Question 8
