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.
Yes. Traditionally, this line is drawn horizontally, with positive numbers to the right, and negative numbers to the left.
It is a 3D representation in two dimensions. Width and height are drawn on horizontal and vertical lines and depth is on an angled line, usually 30 or 45 degrees.
there are three plane surface in a ractangular.
