how do I compare the transform.rotation from a quaternion of the childobject to the key the player pressed?

Hello, I am really bad with syntax. I am making a simple game that there are three patterns that randomly spawn in a designed area and randomly rotate on the z axis. Each pattern has five arrows, and the middle arrow randomly rotates on the z axis. The player must press an arrow key that corresponds to the middle arrow of each pattern to get a point. For example, if the middle arrow is pointing up, then the player presses the up arrow for a point.

To implement this, I use created each pattern and parent them individually with an empty game object. I instantiate the parent objects and I used a Quaternion. For the middle object, I also used a quaternion, but I used a separate script and attach it to the child(2) of each pattern.

The issue I am having how do I compare the transform.rotation from a quaternion of the childobject(2) to the key the player pressed? Thank you in advance.

Code I used for the middle game objects of each pattern.

public class MiddleObjectRot : MonoBehaviour { // Start is called before the first frame update void Start() { MiddleSpawnRandRot(); }

public void MiddleSpawnRandRot() { Quaternion middleSpawnRot = Quaternion.Euler(0, 0, Random.Range(0, 4) * 90); transform.rotation = middleSpawnRot;

     Debug.Log(gameObject.transform.rotation);
 }

}
