I apologize in advance for my ignurince. But I am new and putting in the hours so please be patient Classroom in a book isn’t everything. I am trying make two isometric triangles from a rectangular image and use the pieces as layers within my design. I still consider myself a novice and have grappled with paths and clipping paths as long I can bear. Your advanced wisdom is appreciated and endlessly valuable to me. Thanks, Derek.

Derek,

Your advanced wisdom is appreciated and endlessly valuable to me.

I probably shouldn’t be responding, because I’m an "intermediate newbie" so, I certainly don’t qualify as having advanced wisdom—but,
sometimes the "simple way" works for me until I grasp the "devine wisdom." I’m not good at paths yet either.

If I’m understanding you correctly—(I didn’t know what you meant by "isometric triangles" –I think you mean "isosceles triangles" meaning having two sides of the same dimension)—if I’m wrong, probably disregard my info.

1. Open your rectangle image as a seperate document from your "canvas" that you are creating your artwork.

2. Duplicate your rectangle image layer as insurance in case you screw up. Turn off the eye on the original and work with the duplicate layer.

3. Use the polygon lasso tool and click the "points" of your triangle. When you are back to your starting point, you will see a small circle that indicates "closure"–click and you will have your triangle selected.

4. Go to "Select">save selection and name it left triangle. With your selection still active, create a new layer and use the paint bucket to fill the selected triangle with any color. (That way you can see your selection.)

5. Go back to your working layer of your rectangle image and repeat above steps to create your second triangle following the boundaries of your "colored triangle".(name this selection right triangle)

6. Now go back to your working rectangle and choose "Select">load selection and choose the left triangle. This will result in your triangle being selected on your image—now choose the move tool and move it to your final canvas.

7. Repeat with right triangle.

Hope this works for you. I probably made it sound more complicated than it is—or I could have missed your whole concept—but, I tried.

The "smart people" will have a better way, no doubt.

While I GREATLY appreciate your suggestion, I don’t think I was clear in my original message. I want to divide a rectangular image diagnolly, which will actually create 2 obtuse triangles. ( Triangles with no equal sides) I intend to do this with two seperatly colored images which are IDENTICAL. After doing so, I want to place the separately colored triangles together forming a composite whole of the two original versions. Thus I can do a more unique checker boar pattern. My problem is that I can not create a way to dissect the triangles exactly and precisely. For this checker board to be aesthetically correct, I need precision. Please help me Photoshop friends, I very much want to learn and this design is very important to me. Again, I am not simply asking without trying, (this is important to people like me), I just don’t have the experience and can not conceptualize away from my classroom in a book. Thanks people!

Derek,

Okay, let’s forget the triangle terminology and just concentrate on the end result. I’m sure there are better ways then the method I am describing, but it is simplistic and I believe to be "precise" to accomplish your task.

If both of your rectangle images are the same size and resolution—I stick by the method I described using the polygon lasso and the save selection deal. Did you try it?

If you click on the upper left corner of rectangle and then click on upper right corner of rectangle and then click on lower left corner and complete the triangle with the upper left corner—won’t you end up with two triangles split exactly diagonally through the center?
And then repeat the process reversed for the other side.

(Forget all the paint bucket stuff because if you are disecting diagonally—your starting points are clearly defined by the corners of the rectangle.)

What am I missing? You’ve got me curious so I’d like to learn from your experience.
