The vector clipart library "Arrows" contains 37 arrows you can use to design your presentation slides and illustrations using the ConceptDraw PRO diagramming and vector drawing software.
"An arrow is a graphical symbol ... used to point or indicate direction, being in its simplest form a line segment with a triangle affixed to one end, and in more complex forms a representation of an actual arrow... The direction indicated by an arrow is the one along the length of the line towards the end capped by a triangle. Arrows are also used, in some cultures, as a sign of danger, depending on the direction the arrow is pointing." [Arrow (symbol). Wikipedia]
The example "Design elements - Arrows" is included in the Presentation Clipart solution from the Illustration area of ConceptDraw Solution Park.
