Match the following vocabulary term with its appropriate part of the circle.

• Minor Arc

• Point V

• Secant Line

• Point of Tangency

• Semi-Circle

• Line PR

• Major Arc

Which are true? (MORE THAN ONE)

• A chord has two endpoints on a circle

• A diameter has two endpoints on a circle

• A secant has two endpoints on a circle

• A tangent has two endpoints on a circle

What is the difference between a secant and a tangent

• A tangent is a line and a secant is a line segment

• A tangent passes through a circle once and a secant passes through the circle twice.

• A secant and a tangent are both chords but a tangent goes through the center of the circle

• A secant passes through the circle once and a tangent passes through the circle twice.

What is the formula for? (^angle/₃₆₀)2Πr

• arc length

• area of a sector

• area of a segment

• arc measure
