Yes. Since an inclined plane is slanted, the stairs fit the definition. Another example of an inclined plane would be the seats of a stadium.
Yes as for example the French mathematician Rene Descartes created coordinated geometry which is plotted on the Cartesian plane.
It does not. For an explanation of "focal plane" see the question What is the focal plane?
it was " De plane!De plane!" not the planes boss the plane.
Triangular, Polygon, Shape
A circle is one example of a plane figure that is not a polygon. A V is also not a polygon.
No, but a pentagon is a polygon. A polygon is a plane shape with 3 or more straight sides.
It has a curved surface.
The question is based on a complete misunderstanding of what a polygon is. A plane figure is not necessarily a polygon. The following are some examples of plane figures which are not polygons:a straight linea curvean anglea circlean ellipsea parabola.
No, a polygon must be 2 dimensional and lie on a single plane.
a polygon a polygon * * * * * No it is not! If the line is in that plane then it is the whole line. If not, it is a single point.
no, a polygon is a closed plane figure bounded by straight sides. so, it can have more than three sides.an example would be a rectangle, square, pentagon....
A polygon is a closed plane shape which is bounded by straight lines. A quadrangle is a polygon with 4 sides.
Yes, because a polygon is a plane (flat) figure. By definition, if it is not flat, it cannot be a polygon.
a polygon is a closed plane shape
