## Transformations

**Transformations are changes in position or size of a shape. **

The study of transformations in this section focus on translations or slides, reflections or flips, and rotation or turns. Line symmetry and Rotational symmetry will also be discussed.

## Symmetry

If you fold a shape in half, where the two halves match then the image is said to have line symmetry or mirror symmetry. This folded line is a line of reflection.

**Term**: *Symmetry*: Exact similar part facing each other.

Observe the following pictures carefully and determine the lines of symmetry.

### IDENTIFY THE LINES OF SYMMETRY

First determine if the shape has any lines of symmetry. Imagine the shape is folded along a line that makes the image into two equal parts.

The line of symmetry is drawn broken. Sometimes, a shape has more than one line of symmetry.

Be careful where you draw your line symmetry.

On a sheet, if they were folded, the equal parts would overlap. The parts are symmetrical. This is the first line of symmetry.
