Name
1. Find k. Is it an enlargement or a reduction?
k =
2. k = 3 and the original side is 7. Find the image side.
3. Are all squares similar to each other? Explain.

Answer Key: Exit Ticket

Similar Figures
  1. 10 / 4 = 15 / 6 → k = 2.5, an enlargement (k > 1)
  2. 7 × 3 = 21
  3. Yes. Every square has four 90° angles, and all four sides grow by the same factor, so one square is always a dilation of another.

Quick read: k = 0.4 on #1 means the student divided original by image; 10 on #2 means they added 3. Practice mode in the game lets students pick the "use the scale factor" questions.
