- Line: The single blue line with arrows on both ends.
- Line segment: The purple double-headed arrow (representing a finite segment).
- Ray: The green line with an arrow on one end and a point on the other.
- Parallel lines: The two black lines that never meet.
- Perpendicular lines: The orange cross (intersecting at 90 degrees).
- Intersecting lines (not parallel or perpendicular): The two red lines crossing at an angle other than 90 degrees.
- Right angle: The brown angle formed by two lines meeting at 90 degrees.
- Acute angle: The pink angle smaller than 90 degrees.
- Obtuse angle: The gray angle larger than 90 degrees but less than 180 degrees.
- Straight angle: The brown line with arrows on both ends, forming a 180-degree angle.
Parent Tip: Review the logic above to help your child master the concept of line segment worksheet.
