## What is a real life example of two planes and their intersection?

A real-world example of two planes intersecting is constructing a wall or placing a fence into the ground (so that its bottom is underground “penetrating” the level ground), and therefore the vertical plane (the wall or fence) intersects the horizontal plane, (the level ground).

## What defines a plane?

In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space.

## Is it possible to have a real life infinite plane?

It is not possible to have a real-life object that is an infinite plane because all real-life objects have boundaries.

## What are the ways of naming a plane?

A plane can be named by a capital letter, often written in script, or by the letters naming three non-collinear points in the plane. For example, the plane in the diagram below could be named either plane ABC or plane P .

## Are points not on the same plane?

Lines and line segments that lie on the same plane (and consequently space) are considered coplanar lines. coplanar: when points or lines lie on the same plane, they are considered coplanar. noncoplanar: when points or lines do not lie on the same plane, they are considered noncoplanar.

## How many planes contain the same three collinear points?

Through any three points, there is exactly one plane. SOLUTION: If the points were non-collinear, there would be exactly one plane by Postulate 2.2 shown by Figure 1. If the points were collinear, there would be infinitely many planes.

## How many planes contain two points?

If you have four points and they are not on the same plane (not coplanar), then they define a space. So the simplest Platonic solid is a tetrahedron (a four-sided die), which has four corners. So how many planes contain two given points? An infinite number.

## What determines a line?

In geometry, a line can be defined as a straight one- dimensional figure that has no thickness and extends endlessly in both directions. It is often described as the shortest distance between any two points. Here, P and Q are points on the line. Fun Facts. A line segment is only a part of a line.

## What is a distinct point?

Two distinct points on a line define a line segment (the line segment has a length, the distance between the two points). Similarly, one distinct point on a line defines two rays (intuitively, the ray starting from the point going left along the line, and the ray starting from the point going right along the line).

## What type of word is distinct?

distinct adjective (NOTICEABLE)
