Introduction

Translation is a fundamental concept in geometry, where a figure is moved from one location to another without any change in its size or shape. In this article, we will explore the translation of a triangle with coordinates $F (-2,3), G (-4,1),$ and $H (-2,-2)$ to its image with coordinates $F^{\prime}(0,0), G^{\prime}(-2,-2),$ and $H^{\prime}(0,-5)$ . We will identify the correct rule for this translation and understand its implications.

Understanding Translation

Translation is a transformation that moves a figure from one location to another without any change in its size or shape. It is a one-to-one correspondence between the original figure and its image. In other words, each point in the original figure is mapped to a unique point in the image.

The Translation Rule

To find the correct rule for the translation of the triangle, we need to examine the coordinates of the original triangle and its image. Let's start by looking at the coordinates of the original triangle:

$F (-2,3)$
$G (-4,1)$
$H (-2,-2)$

Now, let's look at the coordinates of the image:

$F^{\prime}(0,0)$
$G^{\prime}(-2,-2)$
$H^{\prime}(0,-5)$

We can see that the x-coordinate of each point in the image is the same as the x-coordinate of the corresponding point in the original triangle minus 2. Similarly, the y-coordinate of each point in the image is the same as the y-coordinate of the corresponding point in the original triangle minus 3.

The Correct Rule

Based on the analysis above, we can conclude that the correct rule for the translation of the triangle is:

$x^{\prime} = x - 2$
$y^{\prime} = y - 3$

This rule indicates that each point in the original triangle is translated 2 units to the right and 3 units down to obtain its image.

Implications of the Translation Rule

The translation rule has several implications for the geometry of the triangle. For example:

The distance between each pair of points in the original triangle is the same as the distance between the corresponding pair of points in the image.
The angles of the triangle are preserved under the translation.
The centroid of the triangle is preserved under the translation.

Conclusion

In this article, we have explored the translation of a triangle with coordinates $F (-2,3), G (-4,1),$ and $H (-2,-2)$ to its image with coordinates $F^{\prime}(0,0), G^{\prime}(-2,-2),$ and $H^{\prime}(0,-5)$ . We have identified the correct rule for this translation as $x^{\prime} = x - 2$ and $y^{\prime} = y - 3$ . This rule indicates that each point in the original triangle is translated 2 units to the right and 3 units down to obtain its image. We have also discussed the implications of the translation rule for the geometry of the triangle.
