Introduction

In geometry, translation is a fundamental concept that involves moving a figure from one location to another without changing its size or shape. In this article, we will explore the concept of translation and apply it to a specific problem involving a rectangle. We will use the translation rule Tβˆ’5,9(x,y)T_{-5,9}(x, y) to find the coordinates of point H' after the translation of rectangle EFGH.

Understanding Translation

Translation is a transformation that moves a figure from one location to another without changing its size or shape. It is a type of rigid motion that preserves the distance and angle between points. In the context of coordinate geometry, translation can be represented by a vector, which is a mathematical object that has both magnitude and direction.

The Translation Rule

The translation rule Tβˆ’5,9(x,y)T_{-5,9}(x, y) indicates that the translation vector is (βˆ’5,9)(-5, 9). This means that for every point (x,y)(x, y) in the original figure, the corresponding point in the translated figure is (xβˆ’5,y+9)(x - 5, y + 9).

Applying the Translation Rule

To find the coordinates of point H', we need to apply the translation rule to the coordinates of point H. The coordinates of point H are given as (βˆ’2,βˆ’3)(-2, -3). Using the translation rule, we can find the coordinates of H' as follows:

Hβ€²=Tβˆ’5,9(βˆ’2,βˆ’3)=(βˆ’2βˆ’5,βˆ’3+9)=(βˆ’7,6)H' = T_{-5,9}(-2, -3) = (-2 - 5, -3 + 9) = (-7, 6)

Conclusion

In this article, we applied the translation rule Tβˆ’5,9(x,y)T_{-5,9}(x, y) to find the coordinates of point H' after the translation of rectangle EFGH. We used the coordinates of point H as the pre-image and found the corresponding coordinates of H' using the translation rule. The result is Hβ€²=(βˆ’7,6)H' = (-7, 6).

The Translation Rule: A Closer Look

The translation rule Tβˆ’5,9(x,y)T_{-5,9}(x, y) is a specific example of a translation vector. In general, a translation vector can be represented as (h,k)(h, k), where hh and kk are the horizontal and vertical components of the vector, respectively. The translation rule can be applied to any point (x,y)(x, y) in the original figure to find the corresponding point in the translated figure.

Applying the Translation Rule: A Step-by-Step Guide

To apply the translation rule, follow these steps:

  1. Identify the translation vector (h,k)(h, k).
  2. Identify the coordinates of the pre-image point (x,y)(x, y).
  3. Apply the translation rule by adding hh to the x-coordinate and kk to the y-coordinate: (x+h,y+k)(x + h, y + k).

Example: Applying the Translation Rule

Suppose we want to apply the translation rule Tβˆ’3,4(x,y)T_{-3,4}(x, y) to the point (2,1)(2, 1). Following the steps above, we get:

  1. Identify the translation vector: (βˆ’3,4)(-3, 4).
  2. Identify the coordinates of the pre-image point: (2,1)(2, 1).
  3. Apply the translation rule: (2+(βˆ’3),1+4)=(βˆ’1,5)(2 + (-3), 1 + 4) = (-1, 5).

Conclusion

In this article, we explored the concept of translation and applied it to a specific problem involving a rectangle. We used the translation rule Tβˆ’5,9(x,y)T_{-5,9}(x, y) to find the coordinates of point H' after the translation of rectangle EFGH. We also provided a step-by-step guide on how to apply the translation rule and an example to illustrate the concept.
