question

A pentagon is transformed according to the rule R 0,180Â°. Which is another way to state the transformation?

question

Figure 2 was constructed using figure 1.
For the transformation to be defined as a rotation, which statements must be true? Check all that apply

answer

The segment connecting the center of rotation, C, to a point on the pre-image (figure 1) is equal in length to the segment that connects the center of rotation to its corresponding point on the image (figure 2).
The transformation is rigid.
Every point on figure 1 moves through the same angle of rotation about the center of rotation, C, to create figure 2.
If figure 1 is located 360Â° about point C, it will be mapped onto itself.
