Introduction

In mathematics, translation is a fundamental concept in geometry that involves moving a figure from one position to another without changing its size or shape. It is an essential concept in understanding various mathematical operations and transformations. In this article, we will explore the concept of translation and how it can be represented using a rule.

What is Translation?

Translation is a transformation that moves a figure from one position to another without changing its size or shape. It involves shifting the figure horizontally and vertically to a new position. The new position of the figure is determined by the translation vector, which is a pair of numbers that represent the horizontal and vertical shifts.

The Rule for Translation

The rule for translation is given by the equation:

T(x, y) = (x - [?], y + [?])

where $T(x, y)$ represents the translated point, and $[?]$ represents the unknown values that we need to determine.

Given Information

We are given two points: $P(7, 5)$ and $P^{\prime}(2, 8)$ . These points are related by a translation, and we need to determine the rule for translation.

Determining the Rule for Translation

To determine the rule for translation, we need to find the translation vector that moves the point $P(7, 5)$ to the point $P^{\prime}(2, 8)$ . The translation vector is given by the difference between the coordinates of the two points:

\begin{align*} \text{Horizontal shift} &= x^{\prime} - x \\ &= 2 - 7 \\ &= -5 \end{align*}

\begin{align*} \text{Vertical shift} &= y^{\prime} - y \\ &= 8 - 5 \\ &= 3 \end{align*}

Therefore, the rule for translation is:

T(x, y) = (x - (-5), y + 3)

T(x, y) = (x + 5, y + 3)

Conclusion

In conclusion, we have determined the rule for translation using the given points $P(7, 5)$ and $P^{\prime}(2, 8)$ . The rule for translation is given by the equation:

T(x, y) = (x + 5, y + 3)

This equation represents the translation vector that moves the point $P(7, 5)$ to the point $P^{\prime}(2, 8)$ . The horizontal shift is $5$ units to the left, and the vertical shift is $3$ units up.

Example

To illustrate the concept of translation, let's consider an example. Suppose we have a point $Q(3, 2)$ and we want to translate it to the point $Q^{\prime}(8, 5)$ . Using the rule for translation, we can find the translated point as follows:

\begin{align*} T(3, 2) &= (3 + 5, 2 + 3) \\ &= (8, 5) \end{align*}

Therefore, the translated point is $Q^{\prime}(8, 5)$ .

Applications of Translation

Translation has numerous applications in mathematics and other fields. Some of the applications of translation include:

Computer graphics: Translation is used to move objects in computer graphics, such as moving a character or an object in a game.
Engineering: Translation is used to design and analyze mechanical systems, such as moving parts in a machine.
Architecture: Translation is used to design and analyze buildings, such as moving a building to a new location.

Conclusion

In conclusion, translation is a fundamental concept in mathematics that involves moving a figure from one position to another without changing its size or shape. The rule for translation is given by the equation:

T(x, y) = (x + 5, y + 3)
