To mirror a ray in a 2-dimensional plane, follow these steps:
- Draw the ray and the line of reflection, which is a straight line that the ray will be reflected across.
- Draw a perpendicular line from the ray to the line of reflection, marking the point of intersection.
- Draw a line that connects the point of intersection to the point where the ray intersects the line of reflection.
- This new line is the reflected ray, which is the mirror image of the original ray across the line of reflection.
Note: The angle between the original ray and the reflected ray will be the same as the angle between the original ray and the perpendicular line.
