Introduction

In geometry, transformations are essential concepts that help us understand how shapes change under various operations. One common type of transformation is a rotation, which involves rotating a shape around a fixed point by a certain angle. In this article, we will explore a triangle transformation problem involving a rotation of 270 degrees. We will apply the transformation rule to find the coordinates of point S'.

The Original Triangle

The original triangle has vertices at points R(1,1), S(-2,-4), and T(-3,-3). To visualize the triangle, we can plot these points on a coordinate plane.

Original Triangle Coordinates

Point	x-coordinate	y-coordinate
R	1	1
S	-2	-4
T	-3	-3

The Transformation Rule

The triangle is transformed according to the rule R0, 270°. This means that the triangle is rotated 270 degrees around the origin (0,0). To apply this transformation, we need to understand how a 270-degree rotation affects the coordinates of a point.

Rotation of 270 Degrees

A 270-degree rotation is equivalent to a 90-degree counterclockwise rotation. When a point (x,y) is rotated 90 degrees counterclockwise, its new coordinates become (-y,x).

Applying the Transformation to Point S

To find the coordinates of S', we need to apply the transformation rule to point S(-2,-4). Using the rotation formula, we can calculate the new coordinates of S'.

New Coordinates of S'

Point	x-coordinate	y-coordinate
S	-2	-4
S'	-(-4)	-(-2)
S'	4	2

Conclusion

In this article, we applied a 270-degree rotation transformation to a triangle with vertices at points R(1,1), S(-2,-4), and T(-3,-3). We used the rotation formula to find the new coordinates of point S'. The final answer is S' = (4,2).

Discussion

This problem demonstrates the importance of understanding geometric transformations, particularly rotations. By applying the transformation rule, we can find the coordinates of a point after a rotation. This concept is essential in various fields, including engineering, physics, and computer graphics.

Introduction

In our previous article, we explored a triangle transformation problem involving a rotation of 270 degrees. We applied the transformation rule to find the coordinates of point S'. In this article, we will answer some frequently asked questions related to this problem.

Q&A

Q: What is the transformation rule R0, 270°?

A: The transformation rule R0, 270° means that the triangle is rotated 270 degrees around the origin (0,0).

Q: How does a 270-degree rotation affect the coordinates of a point?

A: A 270-degree rotation is equivalent to a 90-degree counterclockwise rotation. When a point (x,y) is rotated 90 degrees counterclockwise, its new coordinates become (-y,x).

Q: How do I apply the transformation rule to a point?

A: To apply the transformation rule, you need to use the rotation formula: (x',y') = (-y,x), where (x,y) are the original coordinates of the point.

Q: What are the new coordinates of point S after the transformation?

A: Using the rotation formula, we can calculate the new coordinates of S: S' = (4,2).

Q: Why is the final answer S' = (4,2) and not S' = (-4,2)?

A: The final answer S' = (4,2) is correct because the rotation formula (-y,x) is applied to the original coordinates of S (-2,-4). This results in the new coordinates (4,2).

Q: Can I apply the transformation rule to other points in the triangle?

A: Yes, you can apply the transformation rule to other points in the triangle. For example, you can find the new coordinates of point T by applying the rotation formula to its original coordinates.

Q: What is the importance of understanding geometric transformations?

A: Understanding geometric transformations is essential in various fields, including engineering, physics, and computer graphics. It helps you to analyze and solve problems involving shapes and their transformations.
