Line. A straight path that is endless in both directions.

A Line is a straight path which is endless in both directions.

In Geometry, there are basically four types of lines….They are:

• Horizontal Lines.
• Vertical Lines.
• Parallel Lines.
• Perpendicular Lines.

Worksheet Overview Straight lines are horizontal if they go across from side to side, without going up or down at all. Straight lines are vertical if they go straight up and down, or top to bottom, without going across at all. Lines are slanting if they don’t go straight across or straight up.

There are two different kinds of lines.

• Straight line:
• Curved line:
• (i) Horizontal lines: The lines drawn horizontally are called horizontal lines.
• (ii) Vertical lines: The lines drawn vertically are called vertical lines.

Types of Curved Lines

• Open Curve. A curved line or a curve is said to be open if the endpoints do not meet.
• Closed Curve. A curve is stated to be closed if its starting point is the same as its ending point.
• Simple Curve. A simple curve does not interact itself.
• Algebraic Curve.
• Transcendental Curve.

There are many examples of curved lines like the alphabets – C and S. Whereas the letters A, M, N, L, etc are not the examples of curves since they can be formed by joining the line segments (or straight lines).

Lines can consist of multiple segments, and the line segments can be curved or straight. The line segments are connected by nodes, which are depicted as small squares. CorelDRAW provides various drawing tools that let you draw curved and straight lines, and lines containing both curved and straight segments.

The Curves tool is the most sophisticated tool for changing the color, brightness, contrast or transparency of the active layer or a selection. While the Levels tool allows you to work on Shadows and Highlights, the Curves tool allows you to work on any tonal range. It works on RGB images.

Line quality is also called line weight and simply put, refers to the thickness or thinness of the line. Lines may become wider or thicker in areas where the object itself is thicker. Or lines may become thicker to help indicate a light source. Lines in areas of shadow may be thicker.

It is a term used frequently in art to describe the relative ‘weight’ of the line against the background or support. In simpler terms, lineweight refers to the strength, heaviness, or darkness of a line. Lineweight is governed by the pressure on your drawing tool as you make your line.

A one line drawing, also known as a single line drawing, is a drawing made with just one line. For most artists it is a way to simplify the complex world around us.

In a continuous-line drawing, the artist looks both at the subject and the paper, moving the medium over the paper, and creating a silhouette of the object. Like blind contour drawing, contour drawing is an artful experience that relies more on sensation than perception; it’s important to be guided by instinct.

Blind contour drawing is a drawing exercise, where an artist draws the contour of a subject without looking at the paper.

A continuous line drawing is one in which a single, unbroken line is used to develop the image. As an exercise, continuous line drawing forces the artist to closely observe the perceived lines of the subject.

• Continuous line drawing are produced using Plotters.
• A plotter is a printer that interprets commands from a computer to make line drawings on paper with one or more automated pens.
• Unlike a regular printer, the plotter can draw continuous point-to-point lines directly from vector graphics files or commands.

In art, the term is used to refer to the continuous line in continuous line drawings which is unbroken from the start to the end of the drawing. In this drawing, continuous lines are created by without taking the drawing instrument and gaze from the drawing surface.

The continuous thick line is used to show visible outlines or edges of a component or assembly. This line may be made thin if the drawing is congested and allot of lines are so close to each other that the clarity of the drawing is negatively influenced.

A continuous line graph is a graph that consists of an unbroken line in which both axes represent continuous quantities1. It is used to plot a set of data usually over an amount of time.

Contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. Numbers on the lines give the height in feet. (Sea level is zero.) Lines drawn closely together indicate that a slope is steep.

Sea Level. is the zero contour line. Index Contour. is the line that is shaded darker than the other contour lines.

The space between the contour lines is called the contour interval and represents a specific (set) distance. If the contour interval is 50 feet, the vertical space between the two contour lines is 50 feet.

The elevation difference between two adjacent contour lines is called the contour interval (CI). Usually the contour interval is noted on the map legend. The elevation difference or vertical distance between two adjacent contour lines would be 20 meters (100 : 5 = 20).

A closed contour, inside of which the ground or geologic structure is at a lower elevation than that outside, and distinguished on a map from other contour lines by hachures marked on the downslope or downdip side.
