• CIRCLE

What is an angle whose vertex is the center of the circle?

• Inscribed angle
• Right angle
• Central Angle

It is a segment whose one endpoint is in the center of the circle and the other endpoint is any point on the circle.

• diameter
• radius
• chord

A segment whose endpoints are any of two different points in the circle.

• diameter
• radius
• chord

It is a chord which passes through the center of the circle

• diameter
• radius
• chord

A line in the plane of a circle that intersects the circle at exactly one point.

• secant
• tangent
• segment

A line that contains a chord.
