Not sure if I'm using IsTouching right?

Hi, I’m pretty new to Unity. I’m trying to practice by remaking the game pop the lock and i want it to be so when you press space while the line is on the dot it’ll move somewhere else
heres my code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class space : MonoBehaviour
{
    public Collider2D lineCol;
    public Collider2D dotCol;
    public GameObject dot;

    void Update()
    {
      if(Input.GetKeyDown("space")){
        Debug.Log("spaced");
        if(lineCol.IsTouching(dotCol)){
          //this part doesn't print
            Debug.Log("WORK!!");
       dot.GetComponent<spawn>().Spawn();
        }
      }
    }
 
}


and heres my spawn script:


using System.Collections;
using System.Collections.Generic;
using UnityEngine;

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

  public void Spawn(){
float randomRot = Random.Range(0, 360);
Debug.Log(randomRot);
transform.eulerAngles = new Vector3(0, 0, randomRot);
    }
    
}

let me know if you need more photos or anything

i forgot to add a rigidbody…
