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