Geometry Ch8 Review #32

This is not explained well in the textbook.

First – the translation is the movement of the bat from position B to position C (see chap 8, Lesson 2) A translation is two rotations around a parallel line – or in other words, we moved it over from one place to another.

So he is asking, how far did it move. Or, what is the length of the black line moving from B to C.

Since we can measure the bat to be about 42 mm (with a ruler), the length of the black line is about 24 mm using the same ruler.
