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.  

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
