 Point One of the basic undefined terms of geometry. No length Ray a ray begins at a point and goes on forever in one direction Angle the union of two distinct rays that have a common end point Vertex the common end point of an angle Plane One of the basic undefined terms of geometry. Goes on forever in all directions; two-dimensional and flat. Line One of the basic undefined terms of geometry. A set of points whose length goes on forever in two opposite directions. Line segment the part of a line between two points on the line Intersecting lines two lines meet at a point. That point is the only point that belongs to both lines Intersection all the points 2 figures have in common Parallel lines two lines in a plane that do not intersect End points the points at the end of a line segment Compass instrument used to draw circles. It has two tips � center and pencil. Bisector divides a segment or angle into two equal parts Perpendicular lines two lines that intersect to form four right angles Circle all points in a plane at a constant distance Radius the length of a line segment between the center and circumference of a circle Equidistant equally distant from any two or more points Arc a continuous portion of a circle Congruent having the same size Authorjfloteaches ID58973 Card Setsnow day-math1.txt DescriptionAshley Knight's vocabulary Math 7th grade Geometry Updated2011-01-10T18:24:17Z Show Answers
