Constructing an Angle From Two Rays

This animation shows the basic construction of a geometric angle: a point O, a horizontal ray [Ox), and a second ray [Oy) drawn upward to the right from the same origin. The angle formed between the two rays is highlighted visually, without any numerical value or degree measure. It offers a clean, minimal introduction to the concept of an angle, useful for students beginning geometry who need to understand rays, vertices, and angle formation before measurement is introduced.

The prompt that made it

Créer une animation mathématique propre et élégante. Afficher un point O. Tracer une demi-droite [Ox) horizontalement vers la droite. Puis construire une deuxième demi-droite [Oy) issue de O et dirigée vers le haut à droite. Afficher clairement les deux demi-droites et leurs noms : O, x et y. Montrer l’angle formé par les deux demi-droites. Ne pas utiliser de vecteurs. Ne pas utiliser de degrés. Ne pas utiliser de mesure numérique de l’angle. Ne pas ajouter d’explication. Fond blanc, lignes bleues, style mathématique professionnel.
