Dear Learners,
Welcome! Here's how to use this file to explore Circular Measurement (in Radians) and understand the Central Angle Theorem.
Before You Begin
Take a moment to think about:
- What is circular measurement in radians?
- What is the central angle of a circle?
- How can this file help you understand these concepts better?
- Click the First Play Button
- Watch what happens: the radius becomes equal to the arc on the circle's circumference.
- Now, slide the point "Rakesh Ghimire" to explore it again and understand more clearly.
- Think: How can we prove that 1 radian is a constant angle?
- Click the "Solution" Button
- You will see three more buttons: Next, Back, and Reset.
- Click Next to go through the proof step by step.
- Click Back to review the previous steps.
- Use Reset to start over and clear the steps.
