Academic Vocabulary & Clarification of Terms
Identify
Radius- the distance from the center of a circle to a point on the circle (plural: radii)
Diameter- a line segment that joins two points on a circle and passes through the center of the circle
Chord - a segment whose endpoints are on a given circle
Tangent- geometry: a line in the plane of a circle that intersects a circle at exactly one point
trigonometry: in a right triangle, the ratio of the length of the leg opposite a given acute angle to the leg
adjacent to the same angle
Secant- a line that intersects a circle or some other curve at two points
Inscribed angle- an angle with its vertex on the circle and with sides (rays) that are chords of the circle
Central angle- an angle whose vertex is the center of a circle and whose sides (rays) are radii
Intercepted arc- that part of a circle that lies between two segments, rays, or secants that intersect the
circle
Circumference - the total distance around a closed curve like a circle
Area- a two dimensional space measured by the number of non-overlapping unit squares or parts of unit
squares that can fit into the space
