Description
Solve any triangle with ease — instantly and visually.
Pythagorus doodlus is designed for anyone who works with triangles every day: engineers, builders, surveyors, students, and curious minds. The app was originally created for a friend who is a carpenter and for my sister, an architect — and it shows. Every feature is built to be practical, intuitive, and genuinely helpful in real‑world situations.
Enter any combination of sides or angles, and the app calculates the rest in real time. Watch the triangle update as you type or adjust values. And if a triangle is impossible to construct, the app doesn’t just say “error.”
It visually explains why the triangle can’t exist and provides a clear, simple reason. Perfect for learning, teaching, or avoiding mistakes on the job.
Features
• Hand‑drawn design
A unique interface that looks and feels like sketching a triangle on paper.
• Interactive triangle editor
Tap a side or angle to edit it, then enter its value using the built‑in keyboard.
• Smart geometry engine
Automatically solves triangles from any valid combination of sides and angles.
• Invalid triangle detection
If the values don’t form a real triangle, the app shows a visual explanation and tells you exactly why it doesn’t work.
• Drag‑to‑reshape
Drag the triangle’s corners to shape it freely before entering side or angle values — a simple way to visualize the triangle you’re working on.
• Quick shortcuts
Double‑tap an angle to toggle 90°, or reset values instantly.
• Step‑by‑step tutorial
A friendly guided walkthrough shows you how to edit sides, adjust angles, use shortcuts, and create new triangles.
Whether you’re on a construction site, at your drafting table, or studying geometry, Pythagorus doodlus gives you a playful and powerful way to understand and work with triangles.
