- Line: The single straight line with arrows on both ends.
- Line segment: The straight line with dots on both ends.
- Ray: The straight line with a dot on one end and an arrow on the other.
- Parallel lines: The two horizontal lines that never meet.
- Perpendicular lines: The two lines intersecting at a right angle (L-shape).
- Intersecting lines (not parallel or perpendicular): The two lines crossing each other at an angle that is not 90 degrees.
- Right angle: The corner formed by two perpendicular lines (90-degree angle).
- Acute angle: The small angle less than 90 degrees formed by two rays.
- Obtuse angle: The wide angle greater than 90 degrees but less than 180 degrees.
- Straight angle: The straight line forming a 180-degree angle.
Parent Tip: Review the logic above to help your child master the concept of line ray segment worksheet.
