In the given ⊙C, the central angle is shown.
Grab Point E and move to Point A.
The new ∠DEB in an inscribed angle.
The inscribed ∠ is half of the central ∠.
You can move Points B and D show
more about other inscribed ∠s.
Add a new Point F on the circle.
Create segments FB and FD.
What conjecture can you make
about the measure of ∠DFB?
