Point A is shown at the right.  \nA line segment is a straight row of points that starts at one point and ends at another point. Line segment AB is written as ···AB .  \nA line is a straight row of points that goes on forever in both directions. Line AB is  \nk·l written as AB .  \nA ray is a straight row of points that starts at one point and goes on forever in one  \n·l  \ndirection. Ray AB is written as AB .  \nAn angle is made up of rays, lines, or line segments that meet at a common point. The angle shown on the right can be named / A, / CAB, or / BAC.  \nParallel lines are always the same distance apart and never cross.  \nPerpendicular lines cross and form aright angle, or 90° angle.  \nA  \nA B  \nA B  \nA B  \nA B  \nInvite your child to share what he or she knows about points, lines, rays, and angles by doing the following activity together.  \n©Curriculum Associates, LLC Copying is not permitted.

Together, find examples of real-life objects that are made up of points, lines, rays, and angles.  \n• Give clues to describe the objects to each other without naming the objects. Use some of the geometry vocabulary words that your child is learning about.  \n• Try to guess each object from the other person’s description of it.  \n• Here are some real-life examples you might use:  \n|  |  |  |  |\n| --- | --- | --- | --- |\n\n|  |  |  |\n| --- | --- | --- |\n\nA traffic intersection (perpendicular lines)  \n 348 Lesson 31 Points, Lines, Rays, and Angles ©Curriculum Associates, LLC Copying is not permitted.  \n  Authorized for use by school personnel only.
