3D shapes are three dimensional, just like 2D shapes are two dimensional.

A star! :D
They are solid shapes as for example a pyramid
You have to cut the trapezoid into three shapes. The three shapes will be two triangles and one rectangle or square. You have to find the area of these three shapes and then add all of the three areas up to find the area of the trapezoid.
triangles
it is called geometricly 3-d
3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
No. A sphere is a three dimensional shape which has no polygonal faces. Similarly an ellipsoid, a torus, a paraboloid, hyperboloid etc are 3-D shapes with no polygonal faces.

Three-dimensional shapes, also known as 3D shapes, include several common types such as cubes, spheres, cylinders, cones, and pyramids. Other examples are rectangular prisms, tetrahedrons, and ellipsoids. Each of these shapes has distinct properties related to their faces, edges, and vertices.
Ah, let's paint a happy little picture with shapes! We have the cube, the sphere, and the cylinder. Each one is unique and beautiful in its own way, just like you are unique and special in this world. Keep exploring and creating, my friend.
The three basic shapes are rectangle, triangle, and square
a polygon(or polyhedron) is a three dimensional figure that has straight edges. * * * * * A polygon is 2 dimensional, a polyhedron is 3-d.
There are infinitely many 3-D shapes so it is not possible to name them individually.
Three dimensional shapes are shapes with height, width, and depth. In contrast, two dimensional shapes only have height and width, or length and width.
3 dimensional shapes have breadth, width and depth whereas 2 dimensional shapes have only breadth and width
Because we live in a 3-D world. Everything we see and come into contact with is a 3-D figure. These 3-D figures have three dimensions: length, width, and height.
