Volume: amount of space an object occupies
Sphere: position of points in space that are a fixed distance from a given part called the center of a sphere
Radius: a segment that connects the center of a sphere to any point on the sphere
Hemisphere: half of a sphere
Great Circle: a circle that divides a sphere into two hemispheres
Chord: a line segment whose endpoints are on the circle
Secant: a line that intersects a circle at two points
Tangent: a line that intersects a circle at 1 point
Point of Tangency: a point where the tangent crosses the circle
Congruent Circle: circles with the same radius
Concentric Circle: circles with the same center
Tangent Circle: 2 circles that intersect at one point
Common Tangent: a line that is a tangent to 2 circles
Central Angle: angle whose vertex is the center of the circle
Arc: an unbroken part of a circle consisting of 2 points called the endpoints and all the points on the circle between them
Minor Arc: an arc whose points are on or in the interior of a central angle
Major Arc: an arc whose points are on or in the exterior of a central angle
Semicircle: endpoints of an arc lie on a diameter
Adjacent Arc: arcs of the same circle that intersect at exactly one point
Congruent Arc: 2 arcs that have the same measure
Sector of a Circle: region bounded by 2 radii
Segment of a Circle: region bounded by an arc and its chord
Arc Length: distance along an arc
Inscribed Angle: an angle whose vertex is on the circle and whose sides are the chords of a circle
Intercepted Arc: consists of endpoints that lie on the sides of an inscribed angle
