Any such mapping can be called shear transformation, transvection, or simply shearing. The transformations could be utilized with a shear matrix or transvection, an elementary matrix that represents the addition of a multiple of one row or column to a different. Such a matrix could also be derived by taking the identification matrix and changing one of many zero parts with a non-zero value. In this case, the displacement is horizontal by a factor of 2 where the fixed line is the x-axis, and the signed distance is the y-coordinate. Note that factors on opposite sides of the reference line are displaced in reverse instructions. Shear mappings should not be confused with rotations. Applying a shear map to a set of factors of the aircraft will change all angles between them (except straight angles), and the length of any line section that's not parallel to the route of displacement. Therefore, it is going to usually distort the shape of a geometric determine, for example turning squares into parallelograms, and circles into ellipses.
