Geometry

Current Features:

Lines:

• Supply Coordinates without length
• Supply one coordinate and length (default direction m=0)
• Supply one of the coordinates, length and slope

Circles:

• Supply radius with/without centre

Polygons:

• Supply all coordinates
• Regular polygons when center and length of side is supplied
• Squares
• Rectangles

Currently supports only 'cm' as unit of length.

Can calculate Euclidean-Distance between two points.

Commands for operating (Specials):

• 'clear stack' : removes all points from point stack, preserves all jobs generated.
• 'clear all' : resets the application to the default state
• 'status' : shows current state of the point stack as well as line, circle and polygon jobs
• 'pop [Point Name]' : removes the given point(s) from the point stack
• 'calculate distance <Points_or_coordinates -> Only one of them>' : return distance between the first two points.

Uploading Questions using UK-LANG:

Currently Supports :

• Dictionary of Points : ($dict) : a statement with point-names in capitals and cordinates in form (x, y), dictionary is local to a particular question (#)
• Tangent : ($tangent) : center (center:), radius (radius:), threshold (thresh:), length (length:), intersection (int:)
• Chord : ($chord) : center (center:), radius (radius:), threshold (thresh:), length (length:), intersection (int:)
• Circle : ($circle) : center (center:), radius (radius:), threshold (thresh:), diameter (diamet:)
• Line : ($line) : threshold (thresh:), length (length:), end-points (name:)
• Statatement : ($stat) : stat (stat:), trans (trans:)
• Polygon : ($poly) : vertices (name:)

Guide to Commands:

• (name:),(center:),(int:),(name:) fields have names of points mentioned already in dictionary.

• (trans:) refers to a particular co-ordinate (specified after (trans:)) to which all other co-ordinates are to be translated to. Use this whenever (stat:) has polygons or lines with undefined co-ordinates. REMEMBER all co-ordinates are auto-shifted and not just those which are undefined.

• (stat:) takes only one-line for processing, use multiple (stat:) for multiple lines, to get an idea of how (stat:) works use Auto-Draw. NOTE: Intteligent-Dictionary-Generation feature of Auto-Draw is partially turned off. Specify the points yourself beforehand in the dictionary, in case you are using them in the statments. However, for regular polygons if a name is given then, Dictionary is auto-updated.

• (center:) and (radius:) for tangent and chords refers to the tangent of the circle to which they belong.
