5.4. More special coordinatesUnder \SpecialCoor, not only angles, but the entire pair of coordinates canbe specified using raw PostScript code using the ! signifier. For example,suppose we want to draw a right angled triangle of hypotenuse 4 cm andone angle equal to 50 ◦ , as shown below:A4cm50 It can be easily seen that B has coordinates (4 cos 50 ◦ , 0) and C has coordinates(4 cos 50 ◦ , 4 sin 50 ◦ ). The triangle (sans the labels) can be drawn bywriting these coordinates in PostScript as below:CBMore on CoordinatesCoordinate gridsChanging sizeAnother type of coordinatesMore special coordinatesChanging the systemSetting parametersOnline L A T E X TutorialPart II – GraphicsPSTricks\begin{pspicture}(0,-0.5)(3,3.5)\SpecialCoor\pspolygon[linecolor=Blue]%(0,0)%(!50 cos 4 mul 0)%(!50 cos 4 mul 50 sin 4 mul)\end{pspicture}Here, the top vertex (C in the first figure) can also be specified moresimply in polar coordinates as (4;50). There’s a simpler way to specifyB also. Note that the x-coordinate of B is the same as that of C and itsy-coordinate is 0. Under \SpecialCoor, we can specify the coordinates ofa point by referring to these coordinates (in any form) of two other pointsE Krishnan, CV Radhakrishnan and AJ Alexconstitute the graphics tutorial team.Comments and suggestions may be mailed totutorialteam@tug.org.inc○2002, 2003, The Indian T E X Users GroupThis document is generated by PDFT E X withhyperref, pstricks, pdftricks and pdfscreenpackages in an intel PC running GNU/LINUXand is released under LPPLThe Indian T E X Users GroupFloor iii, sjp Buildings, Cotton HillsTrivandrum 695014, indiahttp://www.tug.org.in£ ¡ ¢ ¤ ¥ ¦ © 15/23
such that the required point has x-coordinate equal to that of the first pointand y-coordinate equal to the y-coordinate of the second point.

Using the technique just described, B can be specified as(4;40|0,0) and E as (4;40|6;40). Thus this figure (without the labels,of course) can be produced as shown below:CB2cmE Krishnan, CV Radhakrishnan and AJ Alexconstitute the graphics tutorial team.Comments and suggestions may be mailed totutorialteam@tug.org.inc○2002, 2003, The Indian T E X Users GroupThis document is generated by PDFT E X withhyperref, pstricks, pdftricks and pdfscreenpackages in an intel PC running GNU/LINUXand is released under LPPLThe Indian T E X Users GroupFloor iii, sjp Buildings, Cotton HillsTrivandrum 695014, indiahttp://www.tug.org.in£ ¡ ¢ ¤ ¥ ¦ © 16/23
