Assertion: agate's structure | /r/CapableOf | show mirror symmetry
Facets:
value: along 4 axes
type: OTHER
Source sentences:
text: This structure shows mirror symmetry along 4 axes (2 of them run through the structure diagonally), and a four-fold rotational symmetry (you can turn the structure around for 90°, 180°, 270°, and 360°, and it will look the same).
text: This is reflected by the fact that structure still shows mirror symmetry along its principal 2 axes
