Strictly according to the question there is an infinite number of points in a plane where you can construct a normal. For each point there is a normal "up". and its continuation on the otherside of the plane ("down").
In a plane mirror, all the normals (imaginary lines perpendicular to the surface) are parallel to each other. This means that the reflection angle is equal to the incident angle, resulting in a virtual image that appears to be the same distance behind the mirror as the object is in front of it.
All points on the circumference of a circle drawn on a plane are equidistant from the single point on the plane which is the center of the circle.
No. Pyramids are three-dimensional, and hence cannot be drawn within a single plane.
A plane is a flat surface - a 2-dimensional surface. A plane shape is a figure, such as a square, a circle, or a wriggly loop on that surface. It has length and width but no height (or thickness).
Yes. Any shape drawn (or printed) on a plane surface is a 2-d shape.
Both. ANY 2-dimensional shape ... that is, a shape drawn in a plane, or on a piece of paper ... has only one surface.
Two dimensional geometry is called "plane geometry" meaning that it occurs on a single surface or plane. The objects used in plane geometry are called plane figures.
The letter V represents a function when drawn on a coordinate plane.
yes, a plane is a falt surface, because infinite flat surface is a plane.
there are three plane surface in a ractangular.
there are four plane surface in a ractangle.
No, the reflecting surface of a sculpture is typically not a plane surface like that of a plane mirror. It often has irregularities, textures, and contours that can distort the reflected image or create unique reflections.
