Copy of Inscribed Angle Theorem
Students:
The directions for this activity can be found below the applet.
Step 2
This angle with vertex B is said to be an inscribed angle of the circle.
This inscribed angle B is said to intercept arc AC.
Use the Angle tool to find and display the measure of this inscribed angle.
4.
The angle with vertex O is called a central angle of the circle. How does the measure of this central angle compare with the measure of the blue arc it intercepts? Use the Angle tool to find and display the measure of this central angle.
How does the measure of the inscribed angle compare with the measure of the central angle that intercepts the same arc? (Feel free to move points A and C around!)
Inscribed Angle Theorem
Complete the following statements: A central angle is_______________the measure of the intercepted arc. An Inscribed Angle is _________________the measure of its intercepted arc.
