📚 Topic Summary
Geometry transformations involve moving or changing a geometric figure without fundamentally altering its shape or size (except for dilations). The main types include translations (slides), rotations (turns), reflections (flips), and dilations (enlargements or reductions). Understanding these transformations is crucial for various applications in math, science, and engineering.
🧠 Part A: Vocabulary
Match the terms on the left with their definitions on the right:
| Term |
Definition |
| 1. Translation |
A. A transformation that flips a figure over a line. |
| 2. Rotation |
B. A transformation that enlarges or reduces a figure. |
| 3. Reflection |
C. A transformation that slides a figure without changing its orientation. |
| 4. Dilation |
D. The original figure before a transformation. |
| 5. Pre-image |
E. A transformation that turns a figure around a fixed point. |
Match the correct letters (A-E) with the numbers (1-5). For example: 1-C, 2-E, etc.
✍️ Part B: Fill in the Blanks
Complete the following paragraph using the words provided below:
A __________ is a transformation in which a figure is turned about a fixed point called the ___________. The amount of turn is measured in __________. A __________ creates a mirror image of a figure. A __________ changes the size of a figure.
Word Bank: dilation, degrees, reflection, rotation, center of rotation.
🤔 Part C: Critical Thinking
Explain, in your own words, how transformations are used in real-world applications. Provide at least two examples.
