Part IV More Inscribed Angles: Questions 1-3
1. Use 
(Circle with Center and Radius) to create a 6 unit radius circle.
2. Use 
(Polygon) to create 2 triangles inside the circle, all sharing 2 vertices AB and the third vertex C and D are on the same arc.
3. Use 
(Angle) to measure ∢ACB and ∢ADB.

3. Use (Angle) to measure ∢ACB and ∢ADB. Part IV More Inscribed Angles: Question 4
Repeat steps 1 to 3 on 2 more circles.
Part IV More Inscribed Angles: Question 5
What do you notice about the inscribed angle measurements?
Part IV More Inscribed Angles: Question 6
Create a circle and a polygon (quadrilateral) with ACB on one arc and ADB on the other, then measure ∢ACB and ∢ADB (opposite angles).
Part IV More Inscribed Angles: Question 6
What relationship exists between these angles?
