Most sponges of the Demospongiae type are considered asymetrical. (Not having symmetry.)
The largest class of sponges is Demospongiae, which includes over 90% of all known sponge species. Their body type is typically characterized by a leuconoid structure, which consists of a complex network of canals and chambers that allows for efficient water flow and filtration.

Demospongiae
Annelids (such as earthworm and leeches) have bilateral symmetry.
most porifera do not have any symmetry
A triangle need not have any symmetry.
A grasshopper has bilateral symmetry. The left side is essentially a mirror of the right. IT doesn't have any other types of symmetry.
One type of symmetry is rotation. The second type of symmetry is translation. The third type of symmetry is reflection.

That depends on what type of triangle it is because an equilateral triangle has 3 lines of symmetry whereas an isosceles triangle has only 1 line of symmetry and any other triangles have no lines of symmetry.
