In this video you will see visual pictures of important circle vocabulary.

The following important circle vocabulary terms are covered.

**Diameter**The Distance across the circle

**Secant**A line that intersects a circle at two points.

**An Arc**is the distance around a fraction of the circumference.

**Minor arc**an arc with a measure less than 180 degrees

**Major arc**an arc with a distance greater than 18- degrees

**Semi-circle**an arc with a measure of exactly 180 degrees

**Central Angle**The

**angle with a vertex in the center of the circle and the endpoints lie on the circle.**

The central angle equals the arc measure

**Inscribed angle is**an angle in which the vertex lies on the circle, and the end point is on the circle

An Inscribed angle equals one half the intersected arc.

**Center**The point of a circle in which all points of the circle are an equal distance away.

**Radius**The distance from the center of the circle to any point on the circle

**Tangent**A line that intersects the circle at one point.

**Area**is the amount of space inside the circle.
