A cube is a good example of a 3D figure when drawn on paper and showing perspective.
A paper is a2 dimensional Figure
No. A triangle is a two-dimensional figure. It has only length and width, but not thickness. It's a flat shape that can be drawn on a piece of paper, whereas solids are 3-dimensional (for example, a pyramid).
Two examples of 2D figures are a square and rectangle drawn on a paper. Both example figures have length and width.
A solid is a 3-D object in which you can see all of the faces, edges, and vertices. A two dimensional figure is on paper and you cannot hold it in your hands.
Yes, it's not 3 dimensional unless it is a box. Everything that is flat on paper is 2 dimensional.
An object cannot be 3-dimensional and plane at the same time since the term "plane" refers to 2-dimensional objects, such as geometric figures drawn on a sheet of paper. However, certain 3-dimensional objects, for instance a cube, are comprised of 2-dimensional (plane) figures (in this case, 6 of them). On the other hand, a sphere has no plane faces (but theortically approaches an infinite number of them) since no aspect of a sphere can be truly represented on a flat (plane) surface. For practical purposes though, each tiny portion of the sphere could be thought of as a plane figure, and a perfect example of this is a road map.
No. I'm a piece of paper.
A two-dimensional object is an object that can be drawn on a flat sheet of paper. It's called "two-dimensional" because it has 2 dimensions . . . length and width, but no height.
a flat object. Ex. a peice of paper, the paper is flat not 3d. not 3D.
A two-dimensional figure, also called a plane or planar figure, is a set of line segments or sides and curve segments or arcs, all lying in a single plane. The sides and arcs are called the edges of the figure. The edges are one-dimensional, but they lie in the plane, which is two-dimensional. The triangle, the pentagon, the hexagon and the circle are just a few plane figures. Prisms and pyramids, for instance, are three-dimension figures.
Area of a trapezoid = (1/2) x (height) x (top length + bottom length). A trapezoid has no volume. It's a 2-dimensional (flat) figure that can be drawn on a piece of paper, and holds no water.
