NettetWhile the space of linear transformations is large, there are few types of transformations which are typical. We look here at dilations, shears, rotations, reﬂections and … In plane geometry, a shear mapping is a linear map that displaces each point in a fixed direction, by an amount proportional to its signed distance from the line that is parallel to that direction and goes through the origin. This type of mapping is also called shear transformation, transvection, or just shearing. An example is the mapping that takes any point with coordinates to the point .
