rotate using transform unity code example

Example 1: how to rotate object unity

public Transform Position; // make reference in inspector

Position.Rotate(x, y, z);

Example 2: transform.rotation

transform.eulerAngles = new Vector3(0, 0, 180);
transform.localEulerAngles = new Vector3(0, 0, 180);
transform.eulerAngles = new Vector3(0, 0, 180);
transform.localRotation = Quaternion
transform.rotation = Quaternion.Euler(0, 0, 90);
