Lesson 5

In Try This 2, you saw that it is possible to perform a dilation followed by a translation to produce an image that has a different size and position than the original. The diagram you produced may have looked like the following.

Transformations tend to be most useful when you need to accurately produce a new object that is similar to an existing object, especially if the object is complex. There are multiple ways to use transformations to produce a shape, and some are easier than others. For example, it may have been easier for Jenara to translate the centre of the drain hole to determine the centres of the waterline holes. She could have then used a -in drill bit and a 2.5-in drill bit and centred on these points to make the holes.
