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