CATEGORY 1
A line that intersects the circle at exactly one point
Tangent
It is the set of all points equidistant from a fixed point called center
CIRCLE
A line segment connecting a point on the circle to its center
An arc measuring more than 180 degrees
Major arc
FALSE. A diameter is a chord.
A line that intersects the circle at two points
Secant
A section of a circle formed by any two points on its circumference
Arc
A line segment connecting any two points on the circle
Chord
An arc measuring less than 180 degrees
Minor arc
TRUE OR FALSE: Congruent arcs are arcs on the same circle or congruent circles.
TRUE
A line joining two points on the circle and passing through the center
Diameter
The region bounded by an arc and the segment joining its endpoints
Segment
An angle with a vertex at the center of the circle subtended by an arc whose endpoints are on the circle
A minor arc is named by how many endpoints?
2
TRUE OR FALSE: A major arc can measure 360 degrees
FALSE
The distance of the two endpoints of the arc
Arc length
The region bounded by an arc and two radii of the circle
Sector
An arc having a measure of exactly 180 degrees
Semicircle
A major arc is named by how many endpoints
3
TRUE OR FALSE: Conguent circles are circles with congruent radii.
TRUE
