For quadrilateral ASDF to be classified as a square, the following conditions must be true:
- All sides must be equal in length.
- All angles must be right angles (90 degrees).
- The diagonals must be equal in length and bisect each other at right angles.
Given the statements you provided, the following need to be true for ASDF to be a square:
- ∠DFW = 90° - This indicates there is a right angle at vertex D, which is necessary for the shape to have right angles.
- ∠SDF = 90° - This indicates there is a right angle at vertex S, which is necessary for the shape to have right angles.
- ∠FWA = 90° - This indicates there is a right angle at vertex F, which is necessary for the shape to have right angles.
The statement ∠SAF = 45° does not need to be true for ASDF to be a square, as all angles in a square are 90 degrees.
The statement ∠AWF = 45° also does not need to be true because it is not required for a square to have any angles of 45 degrees.
In conclusion, the statements that need to be true for ASDF to be a square are:
- ∠DFW = 90°
- ∠SDF = 90°
- ∠FWA = 90°
