Apex Trigger That Counts the Number of Items in its Related Links

I am in the Trailhead playground; I want to know the count of the opportunities in the opportunities related links. I know I could do a roll-up field, but I want to use an Apex Trigger for practice for objects that do not allow the roll-up method. Thanks.
