![]() Note how there are no arrow heads on the line over AB such as when we denote a line or a ray.Įxample: The following is a diagram of two line segments: line segment CD and line segment PN, or simply segment CD and segment PN.Ī ray is one of the basic terms in geometry. We write the name of a line segment with endpoints A and B as “line segment AB” or as. A line segment does not extend forever, but has two distinct endpoints. We may think of a line segment as a “straight” line that we might draw with a ruler on a piece of paper. We say that these figures intersect.Įxample: In the diagram below, line AB and line GH intersect at point D:Įxample: In the diagram below, line 1 intersects the square in points M and N:Įxample: In the diagram below, line 2 intersects the circle at point P:Ī line segment is one of the basic terms in geometry. The point they share is called the point of intersection. The term intersect is used when lines, rays, line segments or figures meet, that is, they share a common point. A point has no length or width, it just specifies an exact location.Įxample: The following is a diagram of points A, B, C, and Q: ![]() We identify this point with a number or letter. We may think of a point as a “dot” on a piece of paper. PointsĪ point is one of the basic terms in geometry. The arrows signify that the lines drawn extend indefinitely in each direction. 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.Įxample: The following is a diagram of two lines: line AB and line HG. We may think of a line as a “straight” line that we might draw with a ruler on a piece of paper, except that in geometry, a line extends forever in both directions. ![]() measurement (How big is it?, How far is it?, …)īelow is the complete resource on Geometry originally created by The Math League.Ī line is one of the basic terms in geometry. art/patterns (designs, symmetries, representations, …).ĥ. navigating/star-gazing (How do I get from here to there?, using maps, …)Ĥ. machines/motion (using a pry-bar, riding a bike, sawing a board, swinging, …)ģ. building/structures (building/repairing a house, laying out a garden, making a kite, …)Ģ. It occurred in all cultures, through at least one of these five strands of human activities:ġ. The visual study of shapes, sizes, patterns, and positions. When working against polygons the fast offset line algorithm is used up to 3 pixelsĪway from the original geometry, after that a full buffer algorithm is used instead, which always providesĬorrect results, but is significantly more expensive.As comprehensively defined by Cornell University’s Math department, Geometry is: When offsetting linesĪ fast offset algorithm is used, which works well at small distances, but can generate visible artifactsĪt higher values. When applied on polygons instead, positive is interpreted as outwards, negative as inwards.Īs most properties, accepts expressions.Ĭare should be taken when using it, as it might become a performance bottleneck. When applied on lines, positive values generate a parallel line on the left hand side, negative values If present, it makes the renderer draw a line parallel to the original one, at the given distance. ![]() It is native to the SE 1.1 specification, but supported also Specifies the distance in pixels into the dasharray pattern at which to start drawing. Starting from version 2.1 dash arrays can be combined with graphic strokes to generate complex line styles with alternating symbols or a mix of lines and symbols. Odd-indexed numbers (first, third, etc) determine the length in pxiels to draw the line, and even-indexed numbers (second, fourth, etc) determine the length in pixels to blank out the line. Default is butt.Įncodes a dash pattern as a series of numbers separated by spaces. Possible values are butt (sharp square edge), round (rounded edge), and square (slightly elongated square edge). Default is mitre.ĭetermines how lines are rendered at their ends. Possible values are mitre (sharp corner), round (rounded corner), and bevel (diagonal corner). Default is 1.ĭetermines how lines are rendered at intersections of line segments. The value is a number are between 0 (completely transparent) and 1 (completely opaque). Specifies the opacity (transparency) of the line. Specifies the width of the line in pixels. Specifies the solid color given to the line, in the form #RRGGBB. Using the standard CSS/SVG styling model. The name attribute indicates what aspect of styling an element specifies, The elements describe the basic styling of the line.Īny number of elements can be specified.
