Cartesian coordinate system
Spatial figure is a three dimensional figure. It is made up of plane figure whose all sides are joined together to form a close figure
It can be any 2-dimensional figure.
polyhedron is often defined as a geometric object with flat faces and straight edges polygon is traditionally a plane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain). .
3-dimensional shapes made by extruding a polygon are called prisms.In this instance it would be a triangular prism.
It is a three dimensional figure of some sort.
None. A polyhedron is 3 dimensional and you cannot make a 2 dimensional shape out of 3D shapes.
It is a figure that is the same as another figure in the plane. A square is the same plane figure as another square, but a cube is same the same plane figure even tho it is made up of 6 squares.
Of rectangles and squares.
3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
Two-dimensional shapes made with perpendicular lines include (but are not limited to) right-triangles, rectangles, octagons, and dodecagons. Three-dimensional shapes made with perpendicular lines include (but are not limited to) cubes, octahedrons, cuboctahedrons, and icosahedrons.
