Why would understanding perpendicular and parallel lines be extremely important to someone in construction? provide an example of how they would use parallel or perpendicular lines in their job.

Understanding perpendicular and parallel lines are extremely important, especially in the engineering field when building infrastructures or houses because they need to calculate how they will keep a building stable. For example, bridges we see have a lot of perpendicular and parallel lines, that's because without those the bridge can't hold itself up, it needs support from the metals that are parallel and perpendicular.

hope this helps!!
