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.
Three pairs of congruent rectangles.
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.

A true statement about polygons is that they are closed geometric figures made up of line segments connected end-to-end. Polygons have a specific number of sides, vertices (corners), and angles. The sum of the interior angles of a polygon can be calculated using the formula (n-2) * 180 degrees, where n is the number of sides. Additionally, polygons can be classified based on the number of sides they have, such as triangles (3 sides), quadrilaterals (4 sides), pentagons (5 sides), and so on.
The three basic shapes are rectangle, triangle, and square
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.
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
