How do I find the end of an object?

I have a sprite that is a straight line, that can be variable lengths and at variable angles, and I've made the point of origin as one end of the line, but I want another line to be created starting at the opposite end. How can I find where that point is?

Try placing an image point in the opposite end of the sprite you are using as a line, and then use that position to place the following line.

Incredible! Thank you so much!
