Circle Vocab Pt 1

Use the diagram to classify the circle part.

Point P

• Center

• Endpoint

• Point of Tangency

Answer explanation

The correct choice is 'Center' because the point P is located at the center of the circle, as indicated in the diagram.

• Diameter

• Chord

• Radius

• Secant

Answer explanation

The part “WY” in the circle diagram is classified as a Chord because it is a line segment that connects two points on the circle.

• Diameter

• Chord

• Radius

• Secant

Answer explanation

The line segment NQ passes through the center of the circle, making it a diameter.

• Diameter

• Chord

• Radius

• Secant

Answer explanation

The correct choice is 'Secant' because a secant is a line that intersects a circle at two points, and the line segment UY intersects the circle at points U and Y.

Use the diagram to classify the circle part.

Point R

• Midpoint

• Endpoint

• Point of Tangency

• Center

Answer explanation

Point R is classified as the Point of Tangency because it touches the circle at exactly one point.

• Central Angle

• Inscribed Angle

Answer explanation

The angle UXY is a Central Angle because it is formed by two radii of the circle intersecting at the vertex of the angle.

• Central Angle

• Inscribed Angle

Answer explanation

The angle MPN is a Central Angle because it is formed by two radii extending from the center of the circle.

• Central Angle

• Inscribed Angle

Answer explanation

The angle UYW is an inscribed angle because it is formed by two chords of the circle and its vertex is on the circle itself.

• Central Angle

• Inscribed Angle

Answer explanation

The angle NQR is an inscribed angle because it is formed by two chords of the circle intersecting at point R.
