Answer:
pyramid, cone, sphere, cube
Step-by-step explanation:
A symmetrical pattern is one that is arranged in such a way that there is a progressive repetition of a pattern. Each pattern formed is the same with respect to each other.
Eva could form series symmetrical patterns with the shapes he has, which depends on the arrangement of the shapes to form desired pattern.
One simple pattern to be formed is;
pyramid, cone, sphere, cube
pyramid, cone, sphere, cube
pyramid, cone, sphere, cube
pyramid, cone, sphere, cube.
Thus, this would generate four symmetrical continuous patterns.
pyramid, cone, sphere, cube : pyramid, cone, sphere, cube : pyramid, cone, sphere, cube : pyramid, cone, sphere, cube.
