We practiced connecting dots with straight lines using a ruler. This will help us in later chapters when it comes to using drawing tools for math questions.
The red line pairs that are touching are perpendicular to each other. The green lines are parallel.
Can you think of another object besides a robot that has straight lines that form parallel or perpendicular line pairs?
