1. Transformations Leslie Paytes 2009

2. What is a transfomation? A transformation changes the position or orientation of a figure a transfomation changes the position or orientation of a figure

3. What do you call the resulting shapes of a transformation? The resulting shapes are called images of the original. Each image is read as prime, double prime, triple prime...

4. Instruction- Vocabulary-Move Mathman to reveal definition Translation figure slides along a straight line without turning Reflection the figure flips across a line of reflection, resulting in the mirror image Rotation figure turns around a fixed point

5. Translation- moving in a straight line without turning Graph a triangle at A(-3,2)B(-5,2)C(-5,5) Graph the translation of this triangle using the rule (x',y')=(x+2, y-4)

6. Reflection: Flip the image across a line to create a mirror image of the original Graph an arrow A(-4,1), B(-6,3) C(-5,6) D(-3,6), E(-2,3) Reflect over the line y=-2

7. Rotation: the figure rotates around a fixed point Rotate triangle ABC 180 degrees around the origin A(-3,1)B(-7,1)C(-7,7) Click on grid to see rotated figure
