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 in many instances, the pantograph has been replaced by other means for enlarging images. what has the pantograph been replaced by?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. marouane unit 3 geometry

Step-by-step explanation:

1.    The pin’s placement helps to make two drawings simultaneously. This is that while drawing an image a copy, which may vary in size, is created at the same time.

2.    The pantograph relates to dilations and similarity due to the use of similar triangles that affect the scale of the second drawing.  

3.    The use of similar triangles illustrates the process of the pantograph because the ratio of similitude is set when determining where to place the pin. When a triangle is moved while tracing a line, along with the outline of the image, an enlarged/reduced version of the image is created by the other pantograph's end.

4.    The pantograph is now obsolete and has been replaced by several different ways of producing duplicates such as photocopying, mass printing, and digital filing.

The writing utensil’s placement facilitates the drawing of two or more lines with a single stroke of the pantograph. This means while drawing an image two or more copies of varying sizes may be created at the same time. The pantograph mirror is used to extend or retract an image.

The operation of a pantograph relates to dilations and similarity in that both of the processes are done on the graph and it is possible to use similar triangles by measuring the size of the triangles. Pantograph contains links that may be arranged in other ways because they contain a parallelogram.

You can use similar triangles to describe the working of the pantograph because the ratio of similitude is set when determining where to put the pin. When one triangle is moved with the part being specific to the point along the outline of the image, an enlarged/reduced version of the image is created by the movement of the other triangle.

Pantograph has been replaced by modern ways of producing duplicates such as photocopying, mass printing, and digital filing. This is because the technique is currently outdated and the fact that it is difficult to use then now due to their complex designs which do not allow users to properly grip an actual writing utensil like the pen.

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
