About this app
Geometric Similarity is an interactive middle-school math app for exploring how similar figures change when the scale factor k changes. Adjust k to see corresponding side lengths multiply by k, area multiply by k², and volume multiply by k³. Three sections combine guided missions with a multiple-choice challenge on similarity ratios, area ratios, and volume ratios.
Use cases
- Middle-school students learning similar figures and scale factors
- Teachers demonstrating length, area, and volume ratios
- Parents supporting practice with proportional geometry
- Learners reviewing k, k², and k³ relationships
Features
- Interactive scale-factor control with corresponding sides based on a 3:4:5 figure
- Visual exploration of area ratios k² and volume ratios k³
- Toggle between area and volume views
- Guided missions covering ratios from 1 to larger scale factors
- Multiple-choice challenge with correct-answer feedback and streak tracking
