Introduction

In mathematics, the concept of translation is a fundamental aspect of 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 right triangle on the coordinate plane, focusing on the transformation of its vertices. We will use the given coordinates of the vertices of triangle ${$ LMN$}$ and apply the concept of translation to find the new coordinates of the vertices after the transformation.

The Original Triangle ${$ LMN$}$

The original triangle ${$ LMN$}$ has vertices ${$ L (7,-3)$}$, ${$ M (7,-8)$}$, and ${$ N (10,-8)$}$. To understand the translation of this triangle, we need to visualize its position on the coordinate plane. The x-coordinate of the vertices represents the horizontal position, while the y-coordinate represents the vertical position.

| Vertex | x-coordinate | y-coordinate |
| --- | --- | --- |
| L | 7 | -3 |
| M | 7 | -8 |
| N | 10 | -8 |

The Translation of the Triangle

The triangle is translated on the coordinate plane, and the coordinates of ${$ L'$}$ are given as ${$ (-1,8)$}$. This means that the vertex ${$ L$}$ has been moved from its original position ${$ (7,-3)$}$ to the new position ${$ (-1,8)$}$. To find the translation vector, we subtract the original coordinates from the new coordinates.

| Coordinate | Original | New |
| --- | --- | --- |
| x | 7 | -1 |
| y | -3 | 8 |
| Translation Vector | (-8, 11) |

Finding the New Coordinates of the Vertices

To find the new coordinates of the vertices ${$ M'$}$ and ${$ N'$}$, we need to apply the translation vector to their original coordinates. The translation vector is ${$ (-8, 11)$}$, which means that we need to subtract 8 from the x-coordinate and add 11 to the y-coordinate of each vertex.

| Vertex | Original Coordinates | Translation Vector | New Coordinates |
| --- | --- | --- | --- |
| M | (7, -8) | (-8, 11) | (-1, 3) |
| N | (10, -8) | (-8, 11) | (2, 3) |

Conclusion

In this article, we have explored the translation of a right triangle on the coordinate plane. We have used the given coordinates of the vertices of triangle ${$ LMN$}$ and applied the concept of translation to find the new coordinates of the vertices after the transformation. The translation vector has been used to find the new coordinates of the vertices, and we have seen that the triangle has been moved from its original position to a new position on the coordinate plane.

Understanding the Concept of Translation

The concept of translation is a fundamental aspect of geometry, and it is used to describe the movement of a figure from one location to another without any change in its size or shape. In this article, we have seen how the translation of a right triangle can be applied to find the new coordinates of its vertices. This concept is essential in mathematics and is used in various fields, including engineering, physics, and computer science.

Real-World Applications of Translation

The concept of translation has numerous real-world applications, including:

Computer Graphics: Translation is used in computer graphics to move objects on the screen without changing their size or shape.

Conclusion

Q: What is the translation of a right triangle?

A: The translation of a right triangle is the movement of the triangle from one location to another on the coordinate plane without any change in its size or shape.

Q: How do you find the new coordinates of the vertices of a triangle after a translation?

A: To find the new coordinates of the vertices of a triangle after a translation, you need to apply the translation vector to the original coordinates of the vertices. The translation vector is the difference between the new coordinates and the original coordinates of the vertex.

Q: What is the translation vector?

A: The translation vector is the difference between the new coordinates and the original coordinates of the vertex. It represents the movement of the vertex from its original position to its new position.

Q: How do you calculate the translation vector?

A: To calculate the translation vector, you need to subtract the original coordinates from the new coordinates of the vertex.

Q: What is the significance of the translation vector in the translation of a right triangle?

A: The translation vector is essential in the translation of a right triangle as it represents the movement of the vertices from their original positions to their new positions.

Q: Can the translation vector be negative?

A: Yes, the translation vector can be negative. This means that the vertex has been moved to the left or down on the coordinate plane.

Q: How do you apply the translation vector to the original coordinates of the vertices?

A: To apply the translation vector to the original coordinates of the vertices, you need to add the x-component of the translation vector to the x-coordinate of the vertex and add the y-component of the translation vector to the y-coordinate of the vertex.

Q: What is the effect of the translation vector on the coordinates of the vertices?

A: The translation vector changes the coordinates of the vertices by adding or subtracting the x and y components of the translation vector from the original coordinates of the vertices.

Q: Can the translation vector be used to translate a triangle in any direction?

A: Yes, the translation vector can be used to translate a triangle in any direction. The x and y components of the translation vector represent the horizontal and vertical movement of the vertices.

Q: How do you determine the direction of the translation vector?

A: The direction of the translation vector can be determined by the signs of the x and y components. If the x-component is positive and the y-component is positive, the translation vector points to the right and up. If the x-component is negative and the y-component is negative, the translation vector points to the left and down.

Q: Can the translation vector be used to translate a triangle in a 3D space?

A: Yes, the translation vector can be used to translate a triangle in a 3D space. The x, y, and z components of the translation vector represent the horizontal, vertical, and depth movement of the vertices.
