Answer 1

To double an angle, you need to construct a copy of the angle and attach it to the original angle. Therefore, the correct response is:

**constructing a copy attached to the original angle.**

### Explanation:
- **Bisecting the angle twice**: This would divide the angle into quarters, not double it.
- **Constructing two of the bisected angles**: This would result in four angles, one-quarter each of the original, thus not doubling it either.
- **Constructing a copy attached to the original angle**: By duplicating the angle and placing the new angle adjacent to the original angle, the two will sum together, effectively creating a new angle that is double the original.
- **Constructing a copy of the bisected angle attached to the original angle**: This would certainly not double the angle but instead would create an angle that is a combination of the original angle and half of it.

Hence, attaching a copy of the original angle (not the bisected one) to itself is the correct method to double the angle.
