**1. What is the difference between an mirror line and an axis of symmetry?**

Axes of symmetry usually lie on a shape.A mirror line is usually part of a reflection of a shape.

**2. Are there any other transformations besides reflection, rotation, translation and enlargement?**

Yes,

shearandstretchareother transformations.

**3. Why do regular octagons not form a tessellating pattern?**

The inside angle of a octagon is 135

^{o}and so when you try to put three of them together with no gaps or overlapping the angles add up to 405^{o}and so they do overlap.See diagram below.

Regular hexagons tessellate perfectly

**4. What happens when an enlargement has a scale factor of 1?**

Not much! The image will be the same size as the object and in the same place.
