Difference between delegate and event handler

I've added a button (button1) on my form. I click on the button, and
automatically a new method is created called, "button1_Click".

I also see that the following line of code is added as well:

button1.Click += new EventHandler(button1_Click);

Just wonder if this line of code is the same as the following:

button1.Click += new delegate(button1_Click);

Click to expand...

The end result is the same.

And EventHandler() is a type of delegate, so the two are functionally
equivalent.
