**1. Why are there no invariant points under a translation ?**

ALL points move the same distance and in the same direction (given by a translation vector) except when the vector has two zeroes then nothing moves!

**2. Are a line and its image always parallel under a translation?**

Yes.

**3. How many points are invariant (do not move) under translation?**

None, but see question 1!

**4. Is a translation an isometry?**

Yes, size and shape stay the same

**5. How is the translation vector found** **?**

Work out how far horizontally (parallel to x-axis) the object has moved then...

Work out how far vertically (parallel to y-axis) the object has moved then...

Put the first number as top number in the vector and the second number as bottom number.
