A stick figure is a very simple type of rawing, generally of the human form, although stick figures of other types of animals are possible (for example, a stick figure dog). In a stick figure, the head is represented by a circle, sometimes embellished with details such as eyes or crudely-scratched-out hair. The neck, arms, legs and torso are all represented by single straight lines (thus the name). The neck and torso are different segments of one straight line.
