Circle set of coplainer points equidistant from a given point center the given point radius a segment starting at the center and ending on the circle Rule- all radii in a circle are equal or congruent chord a segment starting and ending on the circle at different points diameter a chord that contains or goes through the center secant a coplainer line that contains a chord Tangent a coplainer line that intersects a cicle at only one point Point of Tangency the point where the tangent and the circle meet Congruent Circles two or more circles that have congruent or equal radii Concentric circles two or more coplainer circles with the same center sphere the set of points equidistant from a given point (3-D) Common Tangent a coplainer line that is tangent to two coplainer circles Internal Common Tangent a common tangent the intersects the segment joining the two centers External Common Tangent a common tangent that does not intersect the segment joining the two centers Tangent circles two coplainier circles that intersect at only one point internally tangent circles two coplainier circles that are tangent with one inside the other externally tangent circles two coplainier tangent circles that are not inside of each other arc a set of points that are part of a circle starting and ending at different points minor arc an arc that is less than half the circle (two letters) major arc an arc that is more than half the circle (three letters) Semi-Circle an arc that is equal to one half the circle (three letters if possiable) Arc addition postulate if two arcs have a common end point only then the measure of the first arc plus the measure of the second arc equal the measure of the new arc form congruent arcs two arcs on the same circle (or congrunet circles) that have the same or equal measures midpoint of an arc the point on an arc that divides the arc into two equal or congruent parts Inscribed polygon a polygon drawn inside a circle with all vertics on the circle Circumscribed circle a circle drwn around a polygon touching all vertices Inscribed circle a circle drawn inside a polygon touching all sides Circumscribed polygon a polygon drawn around a circle with all sides touching the circle AuthorAnonymous ID146210 Card SetMath Day 1&2 Descriptionvocabulary words Updated2012-04-07T15:31:39Z Show Answers
