What kind of change occurs in a zigzag line?

Correct answer: Sharp angular turns

Answer: B, a zigzag line changes direction through sharp angular turns. It is usually made from straight segments that meet at pointed corners, creating repeated V- or W-like forms. B is correct because the important feature is the sudden change of direction at an angle. A describes a smooth curved or wavy line, where the bends are rounded rather than pointed. C concerns thickness, not the defining path or direction of a line. D describes a straight line, which does not turn. A zigzag line may be thick or thin, but its angular pattern remains its main identity. Memory cue: repeated pointed corners mean zigzag.
