Which symbol is used to show vector quantities?Group of answer choicesArrowTriangleLine

The symbol commonly used to show vector quantities is an Arrow.

Explanation:

In physics and mathematics, vectors are quantities that have both magnitude and direction. To visually represent this in diagrams, arrows are used because they can effectively convey these two essential aspects of a vector. The length of the arrow is proportional to the magnitude of the vector, while the direction in which the arrow points indicates its direction.

For example, when representing velocity, the arrow will show how fast an object is moving (magnitude) and the direction it is moving. Other shapes like triangles or lines might be used in different contexts, but specifically for vectors, arrows are the clear standard.
