You can know how to slide a shape using the T ( a, b ) T ( − 10, 3 ) because the first value is always the x-axis. Lengths of line segments are preserved under translations. To avoid confusion, the new image is indicated with a little prime stroke, like this: P′, and that point is pronounced “ P prime. In general, if a translation in the coordinate plane has a horizontal displacement of units and a vertical displacement of units, then (, ) will be mapped to ( +, + ). Starting with (yx2) and literally replacing (x) by (x-2) gives (yx-22). Note well: when replacing (x) by (x-C) we must pay attention to meaning, not merely appearance. Suppose you have Point P located at (3, 4). The graph of (y(x+1)2) is the same parabola shifted over to the left so as to have its vertex at (-1) on the (x)-axis. The original reference point for any figure or shape is presented with its coordinates, using the x-axis and y-axis system, (x,y). Reflection – exchanging all points of a shape or figure with their mirror image across a given line (like looking in a mirror) Translation Notation Graphical introduction to image translations. Stretch – a one-way or two-way change using an invariant line and a scale factor (as if the shape were rubber) We describe this translation algebraically using the coordinates (x-5, y+3).

For example, we can translate a point by moving it 5 units left and 3 units up. Shear – a movement of all the shape’s points in one direction except for points on a given line (like a crate being collapsed) A translation is a way to move a point or shape by a certain number of units in a certain direction. Rotation – turning the object around a given fixed pointĭilation – a decrease in scale (like a photocopy shrinkage)Įxpansion – an increase in scale (like a photocopy enlargement) Translation – moving the shape without any other change You can perform seven types of transformations on any shape or figure: Translations are the simplest transformation in geometry and are often the first step in performing other transformations on a figure or shape.įor example, you may find you want to translate and rotate a shape. an isometry) because it does not change the size or shape of the original figure. A translation is a rigid transformation (a.k.a.
