The video tutorial explains the inscribed angle theorem, which states that an inscribed angle is half the measure of the central angle subtending the same arc. The instructor begins by defining inscribed angles and central angles, then proves the theorem using a special case where one chord is the diameter. The proof is generalized to other cases, including when the center of the circle is not within the angle. The video concludes by confirming the theorem's validity for all configurations of inscribed angles and central angles.

What is the relationship between an inscribed angle and the central angle subtending the same arc?

• The inscribed angle is twice the central angle.

• The inscribed angle is equal to the central angle.

• The inscribed angle is unrelated to the central angle.

• The inscribed angle is half the central angle.
