How to mark the point, display lines and measure distance in Matlab?

Hello there,

I want to mark the point in the image and check the length.

The attached picture is exactly what I want to do.

1. Click the red dot you want with the mouse.

2. Display a straight line(blue line) connecting the red dot.

3. Automatically creates a green point while bisecting a straight line between two red points.

4. Display a total of five green lines at a 30 degree angle to the blue line based on the green point.

Yesterday I tried to write code using ginput, but since it is a matlab beginner, it is difficult to implement what I want.

Please help me if you have any ideas to help me implement the process I want.

Thanks.. T^T
