Introduction

In this article, we will delve into the concept of rotating a figure 90° clockwise and explore the resulting new figure. We will also list the coordinates for both images, providing a deeper understanding of the transformation process. This analysis is essential in mathematics, particularly in geometry and trigonometry, where rotations play a crucial role in problem-solving.

Understanding Rotations

A rotation is a transformation that turns a figure around a fixed point, known as the center of rotation. In this case, we will be rotating the figure 90° clockwise, which means that the figure will be turned to the right by 90 degrees. This type of rotation is also known as a counterclockwise rotation, as it is the opposite of a clockwise rotation.

Rotating the Figure 90° Clockwise

To rotate the figure 90° clockwise, we need to follow these steps:

Identify the center of rotation: The center of rotation is the point around which the figure will be turned. In this case, the center of rotation is the origin (0, 0).
Determine the angle of rotation: The angle of rotation is 90° clockwise.
Apply the rotation: To apply the rotation, we need to multiply the coordinates of each point by the rotation matrix. The rotation matrix for a 90° clockwise rotation is:
```
| 0  1 |
| -1 0 |
```
This matrix represents the transformation that will be applied to each point.

New Figure and Coordinates

After applying the rotation, the new figure will have the following coordinates:

Point	Original Coordinates	New Coordinates
U (4)	(4, 0)	(0, 4)
U ( )	(0, 0)	(0, 0)
w()	(0, 1)	(1, 0)
w' ( )	(1, 0)	(0, -1)
X(-)	(-1, 0)	(0, -1)
X'( )	(0, -1)	(-1, 0)

Discussion and Analysis

The rotation of the figure 90° clockwise results in a new figure with the same shape and size, but with a different orientation. The coordinates of each point have been transformed according to the rotation matrix, resulting in a new set of coordinates.

Conclusion

In conclusion, rotating a figure 90° clockwise is a fundamental concept in mathematics, particularly in geometry and trigonometry. By understanding the rotation process and applying the rotation matrix, we can transform a figure into a new one with the same shape and size, but with a different orientation. This analysis provides a deeper understanding of the transformation process and is essential in problem-solving.
