What real-world
examples did you describe for
the three ways in which two lines
may be related?
1. Parallel lines: Two train tracks running alongside each other are a real-world example of parallel lines. These tracks will never intersect no matter how far they are extended.
2. Intersecting lines: The corners of a bookshelf where two rows of books meet form intersecting lines. The two lines representing the edges of the bookshelves meet at a point, creating an intersection.
3. Perpendicular lines: The walls of a room meeting the floor at a right angle demonstrate perpendicular lines. The vertical walls and horizontal floor intersect at a 90-degree angle, forming perpendicular lines.
