CIRCLE Flashcards
The area occupied by the circle in a two-dimensional plane.
Area
The number of square units inside that circle.
Area
Distance around the circle.
Circumference
Angles in linear pair are?
Supplementary
Two angles that add up to 180 degrees and form a straight line
Supplementary
Vertical angles are?
Congruent
It has 360 degrees
Circle
It is an arc that is equal to 180 degrees
Semicircle
Part of a circle between a chord and an arc.
Segment
Part of a circle between two radii and arc.
Sector
A line that intersects a circle at two points
Secant
A line that intersects the circle at exactly one point.
Tangent
An arc which is exactly one half of a circle.
Semicircle
A “portion” of the circumference of the circle
Arc
A chord that passes through the center of the circle (twice the radius).
Diameter
A line segment that connects two points on the circle.
Chord
A segment from the center to a point on the circle. (Half the diameter)
Radius
A circle from which all the distances on the points are equal.
Center
Set of points in a plane at a given distance from a given point.
