To understand how to make the circle appear behind the triangle but still in front of the square, let's break down the problem step-by-step.
### Initial Conditions:
1. Square is at the bottom.
2. Triangle is on top of the Square.
3. Circle is on top of the Triangle.
### Goal:
- Move the Circle behind the Triangle but not behind the Square.
### Commands Explanation:
- Bring Forward: This would move the selected object one level up in the stacking order. It won't help here because the circle is already at the top.
- Bring to Front: This would place the selected object on the top-most level. Again, not useful in this scenario because the circle is already at the top.
- Send Backward: This moves the selected object one level down in the stacking order. This is potentially useful because we want to place the circle just behind the triangle.
- Send to Back: This command places the selected object at the bottom-most level. This would place the circle behind both the triangle and the square, which is not what we want.
### Solution:
Given the commands available, we need to move the circle 'just' behind the triangle, i.e., one level down. Thus, the command that accomplishes this is:
Send Backward.
By using the "Send Backward" command, the circle would move down one level:
- Initially: Square < Triangle < Circle
- After "Send Backward": Square < Circle < Triangle
So, the circle gets placed directly behind the triangle and remains in front of the square, which satisfies the condition specified in the question.
Thus the correct command to use is Send Backward.
