Hares and rabbits zigzag when they are being chased by a predator as a way to evade capture. This erratic movement makes it difficult for the predator to predict their next move, allowing the hares and rabbits to escape. Additionally, zigzagging helps them to quickly change direction and utilize their agility to outmaneuver their pursuer. This behavior is a survival strategy that has evolved over time to increase their chances of survival in the wild. **

A zigzag shape can be either convex or concave, depending on the specific angles and orientation of the zigzag. If the angles formed by the zigzag are pointing outwards, the shape is convex. On the other hand, if the angles are pointing inwards, the shape is concave. It is important to analyze the specific angles and sides of the zigzag shape to determine whether it is convex or concave. **
