📚 Topic Summary
Geometric transformations are ways to move or change a shape on a coordinate plane without changing its size or shape (except for dilations, which change size). The main types you'll learn about are translations (slides), reflections (flips), rotations (turns), and dilations (resizing). Understanding these transformations helps you describe how objects move in space and is super useful in fields like art, architecture, and computer graphics!
🧮 Part A: Vocabulary
Match the term with its definition:
| Term |
Definition |
| 1. Translation |
A. A transformation that enlarges or reduces a figure. |
| 2. Reflection |
B. A transformation that “slides” a figure. |
| 3. Rotation |
C. A transformation that “flips” a figure over a line. |
| 4. Dilation |
D. The original figure before a transformation. |
| 5. Pre-image |
E. A transformation that “turns” a figure about a point. |
✍️ Part B: Fill in the Blanks
Complete the following paragraph with the correct terms: reflection, rotation, translation, dilation.
A __________ moves a shape without changing its orientation. A __________ flips a shape over a line. A __________ turns a shape around a point. Finally, a __________ changes the size of a shape.
🤔 Part C: Critical Thinking
Imagine you're designing a tile pattern for a bathroom. Explain how you could use translations, reflections, and rotations to create a repeating design. Be creative! 🌟
