Introduction

In geometry, translation is a fundamental concept that involves moving a shape or a figure from one position to another without changing its size or orientation. When a triangle is translated, its image is formed by moving each of its vertices to a new location. In this article, we will explore how to find the image coordinates of a triangle after it has been translated.

Understanding Translation

Translation is a type of transformation that involves moving a shape or a figure from one position to another. It is a rigid motion, meaning that the shape or figure remains unchanged in size and orientation. The only thing that changes is its position. In the case of a triangle, translation involves moving each of its vertices to a new location.

The Original Triangle

The original triangle has coordinates F(-2,3), G(-4,1), and H(-2,-2). To find the image coordinates of the triangle after translation, we need to understand how the translation affects each of the vertices.

The Translation

The translation involves moving each of the vertices of the triangle to a new location. The new coordinates of the vertices are F'(0,0), G'(-2,-2), and H'(0,-5). To find the image coordinates of the triangle, we need to understand how the translation affects each of the vertices.

Finding the Image Coordinates

To find the image coordinates of the triangle, we need to apply the translation to each of the vertices. The translation can be represented by a vector, which is a mathematical object that has both magnitude and direction. In this case, the translation vector is (2,2), which means that each of the vertices is moved 2 units to the right and 2 units up.

Applying the Translation

To apply the translation to each of the vertices, we need to add the translation vector to each of the coordinates. For the vertex F, the new coordinates are F'(0,0) = (-2+2, 3+2) = (0,5). For the vertex G, the new coordinates are G'(-2,-2) = (-4+2, 1+2) = (-2,3). For the vertex H, the new coordinates are H'(0,-5) = (-2+2, -2+2) = (0,-5).

Conclusion

In conclusion, the image coordinates of the triangle after translation are F'(0,0), G'(-2,-2), and H'(0,-5). The translation involved moving each of the vertices of the triangle to a new location, resulting in a new triangle with the same size and orientation as the original triangle.

Example Problems

Here are a few example problems that involve finding the image coordinates of a triangle after translation:
