Learning Targets
- I can identify the center, vertex, and rays that form an angle. #dok1
- I can illustrate the measure of an angle as the part of a circle that is 'cut out' by the angle's rays. #dok2
- I can explain how the rays of an angle determine the part of a circle that represents its measure. #dok2
Big Ideas
- Angle measures can be represented as parts of a circle formed by its rays starting at the circle's center.
- Understanding the connection between angles and circles helps us visualize and calculate angle measures.
Essential Questions
- How is the measure of an angle shown as a part of a circle?
- What do the center, vertex, and rays represent when illustrating an angle with a circle?
- Why do we use a circle to help measure angles?
- How does the portion of the circle 'cut out' by an angle's rays relate to the size of the angle?
