How Many Transformations?
How many single transformations are there to map the blue square on to the brown square?
Each of the other squares has been created through one of the transformations, as detailed below.
By editing each of these transformations, can you place each square over the brown square?
Describe each transformation fully.
Move the red point on the blue square. By looking at which point on the brown square moves, describe fully the transformation.
- To change the rotation drag the turquoise point that is the centre of rotation or double click in the centre of the turquoise square to change the angle (remember in Autograph you must put a minus sign in front of clockwise angles)
- To change the reflection drag the two purple points to move the purple line of reflection.
- To change the enlargement drag the green point that is the centre of enlargement and double click in the centre of the green square to change the scale factor.
- To change the translation drag the two orange points to change the orange vector.
