What do you recall about transformations in a plane? what is important to remember about transformations? what's the difference between rigid transformations and nonrigid transformations?

1)

Any image in a plane could be altered by using different operations, or transformations. Here are the most common types:

2)

Transformations map one set of points onto another set of points, generally with the purpose of changing the position, size, and/or shape of the figure made up by the first set of points. The first set of points, from the domain of the transformation, is called the set of pre-images, whereas the second set of points, from the range of the transformation, is called the set of images. Therefore, a transformation maps each pre-image point to its image point.

3)

Reflections, translations, rotations, and combinations of these three transformations are "rigid transformations".

      example is dilation.  

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

you should at least use a calculater
