Introduction

In mathematics, a rotation is a fundamental concept that involves turning a figure or a point around a fixed point called the center of rotation. This transformation can be described using various mathematical rules, including matrices, vectors, and functions. In this article, we will explore the concept of rotation and determine the rule that describes the transformation of points under a rotation.

The Given Points and Their Images

We are given three points: A(-3, 4), B(4, -5), and C(1, 6). After a rotation, these points map to A'(4, 3), B'(-5, -4), and C'(6, -1), respectively. Our goal is to determine the rule that describes this transformation.

Analyzing the Transformation

To understand the transformation, let's analyze the movement of each point. We can see that point A is rotated 90 degrees clockwise to point A', point B is rotated 90 degrees counterclockwise to point B', and point C is rotated 90 degrees clockwise to point C'.

Determining the Center of Rotation

The center of rotation is the fixed point around which the transformation occurs. To determine the center of rotation, we can use the midpoint formula. The midpoint of the line segment joining A and A' is ((-3 + 4)/2, (4 + 3)/2) = (0.5, 3.5). Similarly, the midpoint of the line segment joining B and B' is ((4 - 5)/2, (-5 - 4)/2) = (-0.5, -4.5). The midpoint of the line segment joining C and C' is ((1 + 6)/2, (6 - 1)/2) = (3.5, 2.5). We can see that the midpoints of the line segments joining the points and their images are not the same, indicating that the center of rotation is not the origin.

Determining the Angle of Rotation

The angle of rotation can be determined using the slope formula. The slope of the line segment joining A and A' is (3 - 4)/(4 - (-3)) = -1/7. The slope of the line segment joining B and B' is (-4 - (-5))/(-5 - 4) = 1/9. The slope of the line segment joining C and C' is (-1 - 6)/(6 - 1) = -7/5. We can see that the slopes of the line segments joining the points and their images are negative reciprocals of each other, indicating that the angle of rotation is 90 degrees.

Determining the Rule of Rotation

Based on our analysis, we can conclude that the rule of rotation is a 90-degree clockwise rotation around the point (0.5, 3.5).
