The video tutorial covers inscribed angles, intercepted arcs, and related theorems in geometry. It begins with an introduction to key vocabulary and concepts, followed by detailed explanations of inscribed angles and intercepted arcs. The tutorial also discusses inscribed and circumscribed polygons, providing visual examples and theorems. Special cases of inscribed angles are explored, concluding with a summary of the key points.

What is the defining characteristic of an inscribed angle?

• Its vertex is on the circle.

• It has no vertex.

• Its vertex is outside the circle.

• Its vertex is at the center of the circle.

• The arc that is perpendicular to the inscribed angle.

What is an inscribed polygon?

• A polygon with all vertices on the circle.

• A polygon with all vertices inside the circle.

• A polygon with no vertices on the circle.
