#39 Shearing (Skewing)
Shearing (or skewing—they're the same thing) is a hard process to describe in words, but it's something you'll often want to apply to a shape. In general, skewing distorts the relationship between opposite sides of an object. A simple example would be converting a rectangle into a parallelogram with 30-degree angles instead of right (90-degree) angles. You can do this by selecting a path segment and moving it with the Shear tool (Figure 39a).

When you shear (skew), the affected object distorts around the center point of the object. To skew around an anchor point instead, first click with the Shear tool to set an anchor point. In this case, the anchor point is fixed while the rest of the object shears (Figure 39b).
