# Which type of transformation does not preserve orientation?

##### 1 Answer

*Reflection* does not preserve *orientation*.

*Dilation* (scaling), *rotation* and *translation* (shift) do preserve it.

#### Explanation:

Perfect example of "oriented" figure on a plane is the right triangle

To introduce *orientation*, let's position ourselves above the plane and, looking down on this triangle, notice that the way from vertex

*Rotation*, *translation* (shift) or *dilation* (scaling) won't change the fact that the direction

Use now a *reflection* of this triangle relative to some axis. For instance, reflect it relative to a line

The way *orientation* and (2) the transformation of *reflection* does not preserve the *orientation*.
