Describe the image of D first reflected across line l, then across line m.
The image shows two vertical lines with space between. Line l is to the left of line m. On the left side of line l is an upper case D. The D is oriented in the forwards direction with the vertical segment on the left of the arc.

The image of D first reflected across line l will be a mirror image of D on the right side of line l. The orientation of the D will be reversed, with the vertical segment on the right of the arc.
The image of D then reflected across line m will be a mirror image of the previously reflected D on the left side of line m. The orientation of the D will be reversed again, with the vertical segment on the left of the arc.
To describe the image of D first reflected across line l, then across line m:
1. Start with the original position of the letter D. The D is upright with the vertical segment on the left side of the arc.
2. Reflect the D across line l. This means that the D will flip horizontally, with the vertical segment now on the right side of the arc.
3. Take the reflected D and further reflect it across line m. This will result in another horizontal flip, with the vertical segment now back on the left side of the arc.
In summary, the image of D after being reflected across line l and then across line m will have the vertical segment on the left side of the arc, just like the original D.
