We need to list 6 geometric principles represented in the picture.
We can see the vertices of something that looks like leaves, arranged in a spiral.
Those vertices form angles. Also, the leaves seem to be tridimensional, so they have a surface area and a volume.
Also, notice that leaves equidistant from the center of the spiral seem to be congruent.
Therefore, we can list the following types of geometric principles:
• vertices
,
• spiral
,
• angles
,
• surface area
,
• volume
,
• equidistance
,
• congruent
