# 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.

## What does F subscript f mean?

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.
