Matching Pairs Geometry matching gameOnline version This game will help you learn common terminology in geometry. by Niyat Siyum 1 ray 2 line 3 line bisector 4 perpendicular lines 5 parallel lines 6 point 7 vertex 8 angle 9 line segment 10 congruent 11 skew 12 angle bisector 13 plane the same cuts an angle in half or into 2 different angles 2 lines that are not parallel and do not intersect, these lines do not exist within the same plane two lines that intersect at a 90 degree angle a location, named by a single capital or lower case letter, because of its lack of dimensions, this figure has no height or width. cuts a line in half A line segment that goes on forever in 1 direction, and with one endpoint. a common endpoint of two rays or line segments formed from two rays that share a common endpoint a part of a line that gets marked by two endpoint, extends finitely in two directions and is 2 dimensional One dimensional, goes on forever in two directions. To distinguish this from a line segment, arrows are used. A figure that extends forever in all directions,this figure is also 2 dimensional 2 lines that never intersect and exist in the same plane
