To reflect shape A in the line x = -1, you will need to mirror the shape across the vertical line x = -1.
Here are the steps to reflect shape A in the line x = -1:
1. Identify the coordinates of each point in shape A.
2. For each point (x, y), calculate the distance between the point and the line x = -1.
3. Subtract twice the calculated distance from the x-coordinate of each point.
- New_x = 2 * (-1 - x) + x
4. The reflected shape will have the new coordinates (New_x, y) for each point.
By following these steps, you can obtain the reflected shape of A in the line x = -1.
