central and and circumferential ngle
Task
Another way to let students explore the relationship between these two angles is a worksheet with a question, so the student gets feedback on his conclusion.
relationship between a central and a circumferential angle on the same circular arc
Stappenplan
| step 1 |  | Select the Point tool and clik on the circle to create a point C. |
| step 2 |  | Select the Segment tool and click on the points A and C to create a segment. Click on the points B and C to create a second segment. Remark: you can create both segments as well with the commands Segment(AC) and Segment(BC). |
| step 3 |  | Select the Angle tool and click respectively on the points A, C and B to create the circumferential angle in C on the given circular arc AB. |
The circumferential angle on a circular arc equals
