Why were the barb wire in no mans land angles in World War 1?

The barbed wire in no man's land during World War I was often laid out at angles to create obstacles that were more difficult for advancing troops to navigate. This design aimed to maximize defensive coverage and increase the chances of entangling enemy soldiers, making them vulnerable to gunfire. Additionally, angled wire could disrupt coordinated attacks by forcing soldiers to maneuver around it, thereby slowing their advance and reducing their effectiveness in an assault. This strategic placement was a key element in the trench warfare tactics of the time.
