Triangle #01

The triangle

Before going into detail concerning the triangle, We enter the field of Gestalt psychology for a brief explanation of Rubin’s experiment, which indicates that human attention is primarily attracted by vertical and horizontal movements.

The first illustration (1) shows that the area marked with radii is immediately seen as a cross, standing over the disk marked With circles.

On the other hand, the second illustration (2) gives rise to a marked doubt about the relative importance of the oblique cross and the circled background. It can therefore be said with absolute certainty that the human eye first seeks out the vertical and the horizontal. If neither of these dimensions is present, the viewer Will try to imagine them in order to “place” the sign, which will be interpreted in relation to the person’s physiological position, in terms of vertical (force of gravity) and horizontal (standing level).




It is therefore not surprising that the expression of a triangle is always first judged in relation to a vertical or a horizontal. In a square standing on its corner, the triangular form is already present, since the sign is bisected vertically or horizontally in the viewer’s subconscious (3).

If we place the triangle vertically on its apex, it obtains a direction-giving character, with movement transferred from the vertical to the horizontal (4).

The simple triangle is therefore much used as a direction sign, which succeeds so long as the directions are horizontal, left or right. Where the required direction is up, down, or even oblique, this form of direction sign can cause confusion (see description in Section 4, The arrow).

Triangles with a horizontal side 5, 6) form ideal backgrounds for signals (road signs, etc.) because of their symmetry. The triangle with horizontal base (5) conveys an impression of stability and permanence, like a pyramid. It is also the symbol for the expression “Wait,” rather like a mountain, whose only active function is to suffer erosion.

The reversed triangle, on the other hand, standing
on its apex (6), has a much more active character. It
is the symbol of a tool, an action, also of scales. The positioning is felt as a limitation in the long run (one cannot stand on one foot for long).
