# What is a location has no size?

## What is a location has no size?

A point in geometry is a location. It has no size i.e. no width, no length and no depth. A point is shown by a dot. A line is defined as a line of points that extends infinitely in two directions.

## What has a location but no size or shape?

A point is a location in space that does not have size or shape. A postulate is a statement that is accepted as true without proof.

## What is a straight path that goes on forever in two directions?

A line is a straight path that goes on forever in both directions.

## Do planes in geometry continue forever?

A plane is a flat surface that continues forever (or, in mathematical terms, infinitely) in every direction. It has two dimensions: length and width. ... This gigantic piece of paper gives you a sense of what a geometric plane is like: it continues infinitely in two directions.

## Do lines go on forever?

A line is as wide as a point, infinitely thin, having an infinite number of points, (in a straight row), extending forever in both the directions. Any two lines can intersect at only a single point. ...

## Is extended in one direction without end?

A ray is part of a line. It has one endpoint and extends without end in one direction. It is represented with one endpoint and one point on the line. It is named using the endpoint first.

## Which has no end point?

A line has no end points. A line segment has two endpoints. A line segment connects both endpoints. If the two lines cannot meet at any point, they are called parallel lines.

## What does AB with an arrow over it mean?

Lines. A line is one of the basic terms in geometry. ... We write the name of a line passing through two different points A and B as "line AB" or as , the two-headed arrow over AB signifying a line passing through points A and B.

## What does an arrow with two lines mean?

Arrows on lines are used to indicate that those lines are parallel. Copyright © Elizabeth Stapel 2010-2011 All Rights Reserved. If there is more than one pair of parallel lines, additional arrow-heads will be used. So this picture shows that p is parallel to q and r is parallel to s.

## What is an arrow called in geometry?

A line has an arrow on each end. A line is a set of connected points that are infinitely close to each other and continue on forever in both directions, as indicated by the arrows. Two of the points have been named on the line. These are the two points that you will use to name the line.

## What does an arrow above a letter mean in physics?

In physics, you generally use a letter in bold type to represent a vector, although you may also see a letter with an arrow on top like this: The arrow means that this is not only a scalar value, which would be represented by A, but also something with direction.

Frobenius norm

## What does this symbol mean F?

F (symbol): A much used symbol, F stands for fractional concentration; free energy; Fahrenheit; visual field; fluorine; force; filial generation, followed by subscript numerals indicating specified matings such as F1); the amino acid phenylalanine; the coefficient of inbreeding , etc.

## What does R stand for in physics?

R = resistance. R = molar gas constant.

## What is r in physics gravity?

On one hand, that's easy for me to answer: In the gravitational force equation F = GMm/r,2 the r represents the distance between the centers of the two objects. ... When an object is on the surface of a planet, the r value is in fact the planet's radius.

## What does T in physics mean?

vave = average velocity ∆x = displacement ∆t = elapsed time The definition of average ve- locity. ... a = acceleration ∆v = change in velocity ∆t = elapsed time The definition of acceleration.
