Frequently Asked Questions
What is the inscribed angle theorem?
The inscribed angle theorem states that an inscribed angle is half of the central angle that subtends the same arc. Inscribed angle = central angle / 2.
What is an inscribed angle?
An inscribed angle is formed by two chords that share an endpoint on the circle. The vertex is on the circle, unlike a central angle whose vertex is at the center.
