Horizontal lines-In geometry, a horizontal line is one which runs from left to right across the page. It comes from the word 'horizon', in the sense that horizontal lines are parallel to the horizon. The horizon is horizontal. Its cousin is the vertical line which runs up and down the page
Vertical lines-A vertical line is one the goes straight up and down, parallel to the y-axis of the coordinate plane. All points on the line will have the same x-coordinate. In the figure above, drag either point and note that the line is vertical when they both have the same x-coordinate. A vertical line has no slope.
Diagonal lines-A diagonal is made out of a straight line that's set at an angle instead of straight up or across. If you picture a square and draw a line connecting the opposite corners, that’s a diagonal line.
Zigzag line-A zigzag is a pattern made up of small corners at variable angles, though constant within the zigzag, tracing a path between two parallel lines; it can be described as both jagged and fairly regular.
Curved line-Curved lines are softer than straight lines. They sweep and turn gracefully between end points. They are less definite and predictable than straight lines. They bend, they change direction. Curved lines express fluid movement.
Actual line-Actual and Implied lines. Actual lines. Actual lines are marks or objects that are real lines; they exist physically. Examples of actual lines include lines painted on a highway, tree branches, lines incised on the surface of gravestone, telephone poles, neon signs, and words on a page.
Implied line-In art, an implied line is defined as a line that suggests the edge of an object or a plane within an object. The line may be broken by intermittent marks, it may be defined by value, color, or texture, or it may not be visible at all.
Line weight-Line weight is the visual lightness, darkness, or heaviness of a line within a drawing. In any architectural drawing, from a sketch to a construction drawing, the interplay of different relative line weights is used to communicate depth, importance, and proximity.
Gestural line-Gestural lines or gesture drawing is a type of drawing where the artist swiftly and almost carelessly makes lines with the medium. Gesture drawings take ~5 to 10 mins max. They're very quick drawings that establish the foundation or basic layout of the object being drawn.
