Translation in Mathematics

Translation in mathematics refers to the process of moving a shape or an object from one position to another without changing its size, shape, or orientation. This movement can be done in any direction - left, right, up, or down - and by a specified distance.

Key Concepts

When dealing with translations, it's important to understand the following key concepts:

Vector: A vector is a quantity that has both magnitude and direction. In the context of translations, a vector represents the direction and distance of the movement of the shape.
Coordinate Notation: Translations can be described using coordinate notation, where the original coordinates of the points of the shape are shifted according to the specified vector.
Describing Translations: Translations can be described using words, vectors, or coordinate notation.

Example

Consider a triangle with vertices at points A(1, 2), B(4, 3), and C(2, 5). If we want to translate this triangle 3 units to the right and 2 units down, we can describe this translation as a vector v = (3, -2). Using coordinate notation, the new coordinates of the vertices after the translation would be:

A'(1 + 3, 2 - 2) = A'(4, 0)

B'(4 + 3, 3 - 2) = B'(7, 1)

C'(2 + 3, 5 - 2) = C'(5, 3)

Study Guide

Here's a study guide to help you understand and practice translations:

Understand the concept of translation and how it differs from other transformations such as reflection and rotation.
Learn how to describe translations using coordinate notation and vectors.
Practice translating various shapes on the coordinate plane using different vectors.
Explore real-world applications of translations, such as in geography or computer graphics.
Review and master the properties of translations, such as the fact that the size and shape of the object remain unchanged.

By mastering the concept of translation and practicing related problems, you'll be well-prepared to handle any translation-based questions in mathematics.

Grade 6 Curriculum Focal Points (NCTM)

Algebra: Writing, interpreting, and using mathematical expressions and equations

Students write mathematical expressions and equations that correspond to given situations, they evaluate expressions, and they use expressions and formulas to solve problems. They understand that variables represent numbers whose exact values are not yet specified, and they use variables appropriately. Students understand that expressions in different forms can be equivalent, and they can rewrite an expression to represent a quantity in a different way (e.g., to make it more compact or to feature different information). Students know that the solutions of an equation are the values of the variables that make the equation true. They solve simple one-step equations by using number sense, properties of operations, and the idea of maintaining equality on both sides of an equation. They construct and analyze tables (e.g., to show quantities that are in equivalent ratios), and they use equations to describe simple relationships (such as 3x = y) shown in a table.
