Angles

~Angles and lines ate found everywhere in real life~angles and lines are the basis for understanding geometry~Careers such as architecture and engineering rely on knowledge about angles and lines~Understanding angles and how they work can even make you better at playing certain games

~Parallel lines never cross~Perpendicular lines always form right angles~Line segments are part of a line between two endpoints~Rays have one endpoint and go in one direction without stopping~Lines extend in both directions without stopping

Facts

~Straight angles are exactly 180 degrees-straight line, no bend~A right angle, which is also called a square angle is exactle 90 degrees and forms a square where the two lines meet.~An acute angle forms where two lines meet and is less than 90 degrees~An obtuse angle is more than 90 degrees but less than 180 degrees
