Introduction

In geometry, translation is a fundamental concept that involves moving a shape or a point from one location to another without changing its size or orientation. In this article, we will explore the concept of translation and apply it to a given triangle with specific coordinates. We will use the translation rule to find the coordinates of point Y' after the triangle has been translated.

Understanding the Translation Rule

The translation rule given is ${$ (x, y) \rightarrow (x-2, y+1)$}$. This means that for any point (x, y), we need to subtract 2 from the x-coordinate and add 1 to the y-coordinate to get the new coordinates after translation.

Applying the Translation Rule to Point Y

Point Y has coordinates ${$ (-3, 4)$}$. To find the coordinates of Y', we need to apply the translation rule to point Y.

Step 1: Subtract 2 from the x-coordinate

The x-coordinate of point Y is -3. Subtracting 2 from -3 gives us:

-3 - 2 = -5

Step 2: Add 1 to the y-coordinate

The y-coordinate of point Y is 4. Adding 1 to 4 gives us:

4 + 1 = 5

Step 3: Write the new coordinates of Y'

The new coordinates of Y' are (-5, 5).

Conclusion

In this article, we applied the translation rule to find the coordinates of point Y' after the triangle has been translated. We used the given translation rule and the coordinates of point Y to find the new coordinates of Y'. The new coordinates of Y' are (-5, 5).

Example Use Case

Translation is a fundamental concept in geometry and has many real-world applications. For example, in architecture, translation is used to design buildings and structures that need to be moved from one location to another. In computer graphics, translation is used to move objects and characters in a 2D or 3D space.

Tips and Tricks

When applying the translation rule, make sure to subtract the correct value from the x-coordinate and add the correct value to the y-coordinate.
Use the given translation rule and the coordinates of the point to find the new coordinates.
Practice applying the translation rule to different points and shapes to become more comfortable with the concept.
