Design a diagram that demonstrates the principle of reflection without brand references. 

1. Title: “Angle of Incidence = Angle of Reflection”
2. Replace “Luz” with “Ray.”
3. Use a horizontal line labeled “Surface” instead of “Espejo.”
4. Depict two angled lines that represent incoming and reflected rays at a 30° angle.
5. Use simple arrows to indicate the direction of the rays.
6. Label the incoming ray as “Incident Ray” and the reflected ray as “Reflected Ray.”
7. Add a small circular protractor symbol to show the angles.
8. Ensure a clean, minimalist layout with clear typography.
