Jumping Towards Orientation of the character

Hello, I am making a 2d game in wich the character falls on a slope and rotates while falling with a fixed rotation. When touching the ground the character jumps at an angle relative to the slope. I want it to always jump towards the orientation of itself, meaning towards his head, no matter what orientation it has at the moment when is touching ground with its legs. I atached a picture to make myself more understandable and my code so far. I am new to unity and i hope you can help me with this problem. Thank you very much!

private void FixedUpdate() {

  IsTouchingGround = Physics2D.OverlapCircle(groundCheckPoint.position, groundCheckRadius, GroundLayer);
  if (IsTouchingGround)
  {
     rigidBody.velocity = new Vector2(rigidBody.velocity.x, JumpPower);}

void Update() { GetComponent().angularVelocity = Spin; if (Input.GetKey(KeyCode.Space)) { GetComponent().angularVelocity = CtrSpin; } //GetComponent().AddForce(new Vector2(0,JumpPower), ForceMode2D.Impulse); } }
