Why is a triangle connected with direction or movement?

Its pointed part gives direction to the eye

A triangle has corners and at least one clearly pointed part. That point can act like an arrow: it guides the viewer’s eye toward a particular side or direction. Depending on its position and orientation, a triangle may suggest movement, tension, speed, or a strong directional force. This is why artists often use triangular forms when they want the composition to feel active rather than completely still.

Option A is correct because the pointed part gives the eye a directional cue. Option B is false because a triangle has corners, while option C incorrectly compares it with a circle. Option D is also too limited, since a triangle can be a main object, a symbol, or a background form. The important visual principle is that pointed shapes guide attention.
