What are the special features of 3D shapes?
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.
How are the triangle and the square alike?
They are both 2D shapes and have exterior angles that add up to 360 degrees
Has a 2D shape got corners or vertices?
Yes. Corners is simply the more casual term. * * * * * Yes, but not all 2D shapes - a circle or an ellipse, for example, have corners. Nor does an irregular curved line that closes up on itself.
Name two 2d shapes in which the angles of each add up to 360degrees?
362
What is the difference between a 2D and 3D shape?

What is some names of organic shapes?
Organic shapes don't have names. They are random shapes that you make up.

Name of the 2d shapes up to 9 sides?
Triangle Quadrilateral Pentagon Hexagon Heptagon Octagon Nonagon

Can you pick 2d shapes up?
No. If you can pick it up, it has depth (even a millimetre). This means it is 3D. A piece of paper is a very thin cuboid. 2D can only be represented by drawings, images on paper etc., not the paper itself.
What is the difference in 2D and 3D?
2D is a shape or an object that is flat and u can not pick it up, and it has 2 faces. 3D is a shape or an object that is a shape and you cant pick it up and hold it, and it can have as many faces.

Why do the angles around vertexes in truncated icosahedron not add up to 360 degrees?
The angles around the vertexes of a truncated icosahedron (120+120+108) do not add up to 360 because they are not all in the same plane, ie. the polyhedron is a 3D structure not 2D. If the vertex is projected onto a 2D surface the angles become 124:20 +124:20 +111:20 which do add up to 360. Anyone with an IQ greater than their shoe size would know this :-)
What are the names of all the shapes with up to 10 sides?
The names of polygons are: 3: triangle 4: quadrilateral 5: pentagon 6: hexagon 7: heptagon 8: octagon 9: nonagon or enneagon 10: decagon There are, of course, many other shapes with curved sides.
Is a polygon a rectangle or square?
A square is a type of rectangle. A rectangle is a type of polygon. Polygons are just 2D shapes with more than three straight sides, where there are no open ends or lines crossing over each other. Triangle and up, basically.
