Drawing Lines with arrows on both sides.

[Ganapathi]

&nbsp;&nbsp;I am using LineTo and MoveTo function to draw lines. <br>Now I able draw arrows, if the line is horizontal. <br><br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;But I culdn't able to draw arrows for other angled lines. How can I solve this one? If any knows, please tell me.<br><br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
