What are the relationships among radii, chords, tangents, and inscribed and circumscribed angles?

Must be fully explained!

These are all parts of circles.

A radius is the distance from the center of a circle to the edge.

A chord is a line segment from 2 different places on a circle.

A tangent is a line that touches the edge of a circle in only 1 place.

Inscribed angles are inside a circle and circumscribed angles are on the outside of a circle.

Explanation:

Radii : Radii is the plural of radius. A radius is the distance measured from the the center of the circle to one side of the circle touching the circumference of the circle.

Chords : A chord is any straight line segment touching any two points on the circumference of the circle.

Tangents : A tangent is a straight line passing through a point at the circumference of the circle . Tangent is always at right angle to the radius at that point. It passes through only one point at the circumference.

Inscribed angles : Inside a circle when two chords meet at a point, they make an angle called as the Inscribed angle. An inscribed angle is always formed inside the circle.

Circumscribed angle : A circumscribed circle is formed when two tangents of a circle intersect s at a point. A circumscribed angle is always formed outside the circle.
