Discussion Topic 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 linkage, Scheiner was able to produce a second image that was enlarged.
Do some brief research on Scheiner's invention. Describe how the pantograph works and
how it is able to produce an enlarged image.
How does the operation of the pantograph relate to dilations and similarity? How can you
use similar triangles to describe why the pantograph works as it does? Write an
abbreviated paragraph proof using similar triangles to explain the design. In many
instances, the pantograph has been replaced by other means for enlarging images. What
has the pantograph been replaced by? Explain.

superior technology and improved medical knowledge to foster imperialism. quinine enabled europeans

to survive tropical diseases and venture into the mosquito-infested interiors of africa and asia. the combination

of the steamboat and the telegraph enabled the western powers to increase their mobility and to quickly respond

to any situations that threatened their dominance. the rapid-fire machine gun also gave them a military advantage

and was in convincing africans and asians to accept western control. the following table summarizes the
