In 1603, German astronomer Christoph Scheiner began to copy and scale diagrams using an instrument that came to be known as the pantograph. By moving a pencil attached to a mechanical assembly, Scheiner was able to produce a second image that was identical to the first but enlarged. Do some brief research on Scheiner’s invention. What shape is the mechanical assembly based on? How does the operation of the pantograph relate to dilations and similarity?
