(dali mi bannana!) it mean that its a radical of 2 shapes + a triangle divided by guwno
3D shapes don't have lines of symmetry they have plane's of symmetry.
No. Asymmetric shapes do not have any lines (or planes) of symmetry.
Lines of symmetry are 2 dimensional. Planes of symmetry are 3D.
There are several different types of symmetry. Some of these include reflectional symmetry or rotational symmetry. It depends on how the plane has been tessellated.
Cubes, pyramids, cones, and spheres are all 3D shapes.
3D shapes don't have lines of symmetry they have plane's of symmetry.
No because 2d shapes are plane such as polygons but example of 3d shapes are: pyramid, cone, cuboid, cylinder, sphere ... etc
Shapes with an irregular cross-section.
Three dimensional shapes, generally, don't have lines of symmetry, but a circle has an infinite number is symmetry lines. 3D shapes also don't have rotational symmetry either, but a circle has an infinite number of that as well.
it depends on what kind of 3D shape you want. example= A sphere has an infinite amount of symmetry lines
3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
No. Asymmetric shapes do not have any lines (or planes) of symmetry.
not all shapes have lines of symmetry. one example is a triangle.
The fact that all plane shapes have rotational symmetry whose order is at least 1.
3D shapes have edges, sides, and intersecting points
Irregular shapes don't ever have rotational symmetry.
The special features of 3D shapes are they all are 3D which means they are fat but 2D shapes are flat they can not stand up.
