I'm trying to draw two shapes in Adobe Illustrator CS4, but in a somewhat abnormal position.
I've attached an image of the desired effect I'm trying to achieve, and I've obviously gotten there, but my way feels clunky and I'm wondering if there's a better mechanism to do it. (Do note, this is my first Illustrator project ever.)
I want to draw a triangle, and then on the top-right edge I want a rectangle rotated and skewed so that the bottom-left corner is above and parallel to the top-right edge of the triangle, and the top-left edge of the rectangle (which is a parallelogram at this point) is coincident with but not in the same position as the top-left edge of the triangle.
My current method is to create a "Guidelines" layer, where I draw an equilateral triangle and convert it to a Guide. Then I draw the triangle and place it, then draw the rectangle and right-click → transform → rotate 60 degrees, then position and size it to where I hope it belongs, as I want the bottom corner of the parallelogram in vertical alignment with the right corner of the triangle, and then shear it at -150 degrees, along the 60 degree angle axis.
Then I free-hand move each corner until everything "looks right", which involves many instants of trial-and-error, and I get an imperfect result.
This seems like a lot of free-handing, because when I try to resize the parallelogram (if I shear first before positioning) it becomes very much skewed, I would like to maintain the angles of it, as they work with my intentions.
I've hand-drawn the red vertical line to indicate the intended alignment at that corner, the guides should indicate the desired effect with the remainder of the alignments, though they're not perfect. I would prefer the resultant shape to be perfectly aligned into my guide-lines, but freehanding it worked good enough.
