Boolean OperationsThe boolean operations offer by Keynote are Unite, Subtract, Intersect, and Exclude:
First things first, the boolean operations are found in Keynote on the Format panel, under the Arrange tab. The operations are only shown when two or more shapes are selected, like shown in the figure above. With the first three operations one can quickly make a shape like this:
Editing ShapesIn this tutorial, we are going to go for this diagram
1. Add a square and make it editable. Right Click on the selected shape and Left Click on Make Editable.
4. Repeat on the opposite side and select both new edges (points). Repeat step 3 on the left side and then holding the Shift key click on the both new points.
7. Lets speed up! In two the of the shapes, remove one of the newly added edges on opposite sides. To remove a edge go into Edit Mode (Step 1), select the vertex, and either press the Delete Key of Right Click and click on Delete. The result should look like this:
8. Resize the shapes. This is an import point, The usual resizing tool will deform the shape and since we want matching triangles, usual resizing is evil. This illustrates the issue:
After aligning and resizing this is the result:
9. Add a rectangle and three triangles...something like this:
10. Combine the shapes with the unite operation. So let's do that by selecting all four shapes and going to the Arrange Tab in the Form Panel and click on Unite.
11. Align the triangles with the guidelines (yellow lines). Similar as in Step 8 select the nodes and move them until they fit:
So that's that! The upper should be easy now.
