🔢 Grade 8 • 🟦 Transformations and Similarity

Transformations and Similarity

Describe translations, reflections, rotations, and dilations, then use them to explain congruence, similarity, and scale relationships.

📋 What You'll Learn

  1. 1 Describe translations, reflections, and rotations using clear geometric language
  2. 2 Use dilations and scale factors to explain similar figures
  3. 3 Decide when a transformation preserves size and when it changes size
  4. 4 Connect transformations to congruence, similarity, and coordinate reasoning
