**Transformations-Kevin Bond**

Translations

Moving a shape, without rotating or flipping it. The shape still looks exactly the same.

Rotations

There is a central point that stays fixed and everything else moves around that point in a circle. A "full rotation" is 360 degrees.

Reflection

An image or shape as it would be seen in a mirror. A flip over a line.

Questions

Summary

**Transformations**

Transormations--moving a shape so that it is in a different position, but still has the same size, area, angles and line length.

Types of transformations

Examples of Translations

Examples of Rotations

Examples of Reflections

The graph on the left shows an example of a transformation. Which transformation is shown?

rotation

translation

reflection in origin

Answer

Reflection in origin

Question

If a reflection in the line y =-x occurs, the the rule for this reflection is?

1) (x,y)----(x,-y)

2) (x,y)----(-x,y)

3) (x,y)----(y,x)

4) (x,y)----(-y,-x)

Answer

4) (x,y)----(-y,-x)

Question

Which transformation turns a figure?

Answer

Rotation

Transformations-same shape, size, and same measurement, BUT different position.

Reflection=mirror line=flip

object vs image

Translation=sliding a shape around

sliding-up/down and/or left/right

Rotation=turn

turn=moving around a point

move=clockwise/counterclockwise

amount of movement=degrees
