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 examine the given coordinates of the original triangle and the translated triangle, and determine the rule that was applied to achieve the translation.

Original Triangle LMN

The original right triangle LMN has vertices ${$ L (7,-3)$}$, ${$ M (7,-8)$}$, and ${$ N(10,-8)$}$. This triangle is a right-angled triangle with the right angle at vertex M. The coordinates of the vertices are given in the Cartesian coordinate system, where the x-coordinate represents the horizontal distance from the origin, and the y-coordinate represents the vertical distance from the origin.

Translated Triangle LMN

The triangle is translated on the coordinate plane, resulting in the coordinates of ${$ L^{\prime}$}$ being ${$ (-1,8)$}$. This means that the original triangle LMN has been moved to a new location on the coordinate plane, and the coordinates of its vertices have changed accordingly.

Determining the Translation Rule

To determine the translation rule that was applied to the triangle, we need to examine the change in the coordinates of the vertices. The original coordinates of vertex L were (7, -3), and the translated coordinates are (-1, 8). This means that the x-coordinate has changed from 7 to -1, and the y-coordinate has changed from -3 to 8.

Horizontal Translation

The change in the x-coordinate from 7 to -1 indicates a horizontal translation of the triangle. The triangle has been moved to the left by 8 units, resulting in a new x-coordinate of -1.

Vertical Translation

The change in the y-coordinate from -3 to 8 indicates a vertical translation of the triangle. The triangle has been moved upwards by 11 units, resulting in a new y-coordinate of 8.

Translation Rule

Based on the changes in the coordinates of the vertices, we can determine the translation rule that was applied to the triangle. The translation rule is a combination of a horizontal translation of 8 units to the left and a vertical translation of 11 units upwards.

Conclusion

In conclusion, the translation of the right triangle LMN on the coordinate plane resulted in a change in the coordinates of its vertices. By examining the changes in the coordinates, we were able to determine the translation rule that was applied to the triangle. The translation rule is a combination of a horizontal translation of 8 units to the left and a vertical translation of 11 units upwards.

Understanding Translation in Geometry

Translation is an essential concept in geometry, where a figure is moved from one location to another without any change in its size or shape. Understanding the translation rule that is applied to a figure is crucial in geometry, as it allows us to analyze and solve problems involving the movement of figures on the coordinate plane.

Real-World Applications of Translation

Translation has numerous real-world applications in fields such as engineering, architecture, and computer graphics. In these fields, translation is used to move objects or figures from one location to another, taking into account the constraints of the environment and the requirements of the problem.
