让我一步一步知道这到提题的答案---**Question 5: C'est possible** M est un point de la demi-droite d'origine A passant par B. Il est à 12 cm de A. Il est donc hors de la feuille. Pourtant je peux construire son symétrique M' par rapport à (d), sans rajouter une feuille de papier. Comment est-ce possible ? Explique ta réponse. EXPLICATION : **Geometric Figure Description:** * **Type:** Geometric diagram showing a line, a ray, and points. * **Elements:** * A straight vertical line labeled "(d)" on the right side. * A ray originating from point A, passing through point B, extending towards the top right. This represents the demi-droite (ray) of origin A passing by B. * Point A is located on the line (d). * Point B is located on the ray originating from A, to the right and slightly above A. B is also to the right of the line (d). * A red line segment goes from point A downwards along the line (d). * A blue line segment connects point A to point B. * **Relative Position:** Point A is on line (d). Point B is on the ray starting from A and passing through B. The ray extends away from A in the direction of B. Line (d) appears roughly vertical in the context of the drawing. * **Labels:** Points A, B, line (d). * **Annotations:** The question mentions a point M on the ray at 12 cm from A, which is off the page. It asks about constructing the symmetric point M' with respect to line (d). M is not shown in the diagram.
