Geometric Term Example A point is an exact location in space. A A line is a straight path of points that goes on and on in opposite directions. A line segment is part of a line with two endpoints. A ray is a part of a line that has one endpoint & continues on forever in one direction. B C D Label What You Say point A Point A BC Line BC Line CB CB E DE NP F G A ray is named with its endpoint first. Line Segment DE Ray NP Geometric Term Intersecting lines are lines that cross at exactly one point. Intersecting lines form four angles. Parallel lines are lines that are always the same distance apart. Parallel lines NEVER intersect. Perpendicular lines are lines that intersect to form four right angles. Example H Label K X J L D E F G M P N O HL and JK intersect at point X. Line DE is parallel What You Say Line HL intersects Line JK at point X. Line DE is parallel to line FG. to Line FG. Line MN is perpendicular to Line NP. Line MN is perpendicular to Line NP. The difference between intersecting and parallel lines is : ● ● intersecting lines make 2 acute angles and 2 obtuse angles. perpendicular lines make 4 right angles.
