๐ Topic Summary
Translation in math means moving a shape without rotating or resizing it. Imagine sliding a puzzle piece across the table โ that's a translation! On a coordinate plane, we describe translations by how many units we move the shape horizontally (left or right) and vertically (up or down). These movements are described using coordinates, and by working through these worksheets, it'll become easy to read and understand. Practice makes perfect!
๐ค Part A: Vocabulary
Match the term to its definition:
| Term |

| 1. Coordinate Plane |
A. The horizontal number line |
| 2. Translation |
B. A plane spanned by the x-axis and y-axis on which points are represented by coordinates. |
| 3. X-axis |
C. The vertical number line |
| 4. Y-axis |
D. The point (0,0) |
| 5. Origin |
E. Sliding a figure without rotating or resizing it. |
โ๏ธ Part B: Fill in the Blanks
When we ________ a figure, we are moving it without changing its size or shape. This movement can be described as moving a certain number of units to the ________ or ________, and a certain number of units ________ or ________. The original figure is called the pre-image, and the new figure after the translation is called the ________.
๐ค Part C: Critical Thinking
Imagine you have a triangle on a coordinate plane. How could you describe its translation to someone who can't see the plane? What information would you need to give them?
