cross section
It is the cross-section of the figure by the plane.
Since a frustum is a portion of a solid, three-dimensional figure, and a rectangle is a plane, two-dimensional figure, there can be no such thing as the frustum of a rectangle.
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.
An arrow can be a polygon. A polygon is any two dimensional plane figure. An arrow can, obviously, be a three dimensional object.
A decagon. A two-dimensional shape (plane figure, or polygon) which has ten sides is a decagon. A three-dimensional shape (polyhedron) which has ten sides (plane faces) is a decahedron.
It is the cross-section of the figure by the plane.
Cross Section
The first step in describing the figure that results from the intersection of a plane with a three-dimensional figure is to identify the equation of the plane and the equation of the three-dimensional figure. Next, you need to determine the points where the plane intersects the three-dimensional figure by substituting the plane's equation into the figure's equation. This will produce a new equation representing the intersection, which can then be analyzed to identify the resulting geometric shape.
The first step in describing the figure that results from a plane intersecting a three-dimensional figure is to identify the equation of the plane and the equation of the three-dimensional figure. Next, analyze the geometric properties of both the plane and the solid to determine the nature of the intersection. This involves considering the orientation and position of the plane relative to the solid to predict the resulting intersection shape, such as a point, line, or curve. Finally, you can visualize or sketch the intersection to aid in understanding the resultant figure.
The first step in describing the intersection of a plane with a three-dimensional figure is to identify the equations or defining properties of both the plane and the 3D figure. This involves determining the orientation and position of the plane relative to the figure. Once that is established, you can analyze how the plane cuts through the figure to predict the shape of the intersection, which could be a point, line, or curve depending on the specific geometries involved.
vertex
Two dimensional object is a plane figure where as three dimensional object is solid (space) figure.
The plane is in two dimensional and the space figure is in three dimensional.
An edge.
Presumably, the "three dimensional triangular plane" is actually a two dimensional plane which is "tilted" with respect to the axes. The point of intersection is simply the coordinates of the solution to the simultaneous equations for the line and the plane.
false
No, a square is a two dimensional plane figure.
