Introduction

In mathematics, the concept of translation is a fundamental transformation that involves shifting a point or a shape from one location to another on the coordinate plane. This transformation does not change the size or shape of the object, but rather its position. In this article, we will explore the translation of a right triangle on the coordinate plane, using the vertices of the triangle as a reference.

Understanding the Initial Triangle

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

Translation of the Triangle

The triangle is translated on the coordinate plane so that the coordinates of ${$ L' $}$ are ${$ (7 + 3, -3 + 2) $}$. This means that the vertex ${$ L $}$ is shifted 3 units to the right and 2 units upwards. Similarly, the vertex ${$ M $}$ is shifted 3 units to the right and 2 units upwards, resulting in new coordinates ${$ (7 + 3, -8 + 2) $}$. The vertex ${$ N $}$ is also shifted 3 units to the right and 2 units upwards, resulting in new coordinates ${$ (10 + 3, -8 + 2) $}$.

Determining the New Coordinates

To determine the new coordinates of the vertices, we need to apply the translation to each vertex. The translation vector is ${$ (3, 2) $}$, which represents the horizontal and vertical shift. We add this vector to each vertex to obtain the new coordinates.

For vertex ${$ L $}$, the new coordinates are ${$ (7 + 3, -3 + 2) = (10, -1) $}$.
For vertex ${$ M $}$, the new coordinates are ${$ (7 + 3, -8 + 2) = (10, -6) $}$.
For vertex ${$ N $}$, the new coordinates are ${$ (10 + 3, -8 + 2) = (13, -6) $}$.

Visualizing the Translation

To visualize the translation of the triangle, we can plot the initial and final positions of the vertices on the coordinate plane. The initial position of the triangle is represented by the vertices ${$ L(7, -3) $}$, ${$ M(7, -8) $}$, and ${$ N(10, -8) $}$. The final position of the triangle is represented by the vertices ${$ L'(10, -1) $}$, ${$ M'(10, -6) $}$, and ${$ N'(13, -6) $}$.

Conclusion

In conclusion, the translation of a right triangle on the coordinate plane involves shifting the vertices of the triangle from one location to another. The translation vector represents the horizontal and vertical shift, and is added to each vertex to obtain the new coordinates. By applying the translation to each vertex, we can determine the new coordinates of the vertices and visualize the translation on the coordinate plane.

Example Problems

Problem 1: Translate the triangle ${$ \triangle ABC $}$ so that the coordinates of ${$ A' $}$ are ${$ (2 + 4, 3 + 1) $}$. Find the new coordinates of the vertices ${$ B $}$ and ${$ C $}$.

Solutions

Solution 1:
- The translation vector is ${$ (4, 1) $}$.
- For vertex ${$ B $}$, the new coordinates are ${$ (2 + 4, 4 + 1) = (6, 5) $}$.
- For vertex ${$ C $}$, the new coordinates are ${$ (3 + 4, 5 + 1) = (7, 6) $}$.
Solution 2:
- The translation vector is ${$ (2, 3) $}$.
- For vertex ${$ E $}$, the new coordinates are ${$ (5 + 2, 1 + 3) = (7, 4) $}$.
- For vertex ${$ F $}$, the new coordinates are ${$ (6 + 2, 2 + 3) = (8, 5) $}$.

Introduction

In our previous article, we explored the translation of a right triangle on the coordinate plane. We discussed the concept of translation, the initial and final positions of the triangle, and the new coordinates of the vertices. In this article, we will answer some frequently asked questions about the translation of a right triangle on the coordinate plane.

Q&A

Q1: What is the difference between translation and rotation?

A1: Translation and rotation are two different types of transformations. Translation involves shifting a point or a shape from one location to another on the coordinate plane, while rotation involves rotating a point or a shape around a fixed point.

Q2: How do I determine the new coordinates of the vertices after translation?

A2: To determine the new coordinates of the vertices after translation, you need to add the translation vector to each vertex. The translation vector represents the horizontal and vertical shift, and is added to each vertex to obtain the new coordinates.

Q3: Can I translate a triangle by a negative translation vector?

A3: Yes, you can translate a triangle by a negative translation vector. A negative translation vector represents a shift in the opposite direction, and will result in a new position for the triangle.

Q4: How do I visualize the translation of a triangle on the coordinate plane?

A4: To visualize the translation of a triangle on the coordinate plane, you can plot the initial and final positions of the vertices. The initial position of the triangle is represented by the vertices, while the final position is represented by the new coordinates of the vertices.

Q5: Can I translate a triangle by a translation vector that is not a multiple of the unit vector?

A5: Yes, you can translate a triangle by a translation vector that is not a multiple of the unit vector. However, the translation vector must be a scalar multiple of the unit vector, and must be added to each vertex to obtain the new coordinates.

Q6: How do I determine the translation vector for a given triangle?

A6: To determine the translation vector for a given triangle, you need to find the difference between the initial and final positions of the vertices. The translation vector is the vector that represents the horizontal and vertical shift, and is added to each vertex to obtain the new coordinates.

Q7: Can I translate a triangle by a translation vector that is not a vector?

A7: No, you cannot translate a triangle by a translation vector that is not a vector. A translation vector must be a vector, and must be added to each vertex to obtain the new coordinates.
