**Lines,**Line Segments, Rays**Line**Line- a straight path that goes in two directions without ending. B A AB Read: “Line AB”**Ray**A ray has one end point and goes on forever in only one direction. D C CD Read: “Ray CD”**Line Segment**A line segment has two endpoints. F E Read: “Line Segment EF” EF**Your Turn!**Identify the type of line: line, ray, or line segment. Line Segment**Your Turn!**Identify the type of line: line, ray, or line segment. Line**Your Turn!**Identify the type of line: line, ray, or line segment. Ray**Your Turn!**Identify the type of line: line, ray, or line segment. Line**Your Turn!**Identify the type of line: line, ray, or line segment. Ray**Your Turn!**Identify the type of line: line, ray, or line segment. Line Segment**Parallel Lines**Parallel Lines- lines that never cross or become further apart from each other. K J M L Read: “Line JK is parallel to line LM” ║ LM JK**Intersecting Lines**Intersecting Lines- lines that cross each other. O R Q P intersects OP QR**90º/Right Angle**Perpendicular Lines Perpendicular Lines- lines that cross or meet each other to form square corners (90º angle). U T S Read: “Line ST is perpendicular to line UV” V UV ST ┴**Your Turn!**Identify if the lines are parallel, perpendicular, or intersecting (not at a perpendicular angle).
