Drawing line to non-parallel line

I couldn't come up with  good title but this what I'm looking to do.

Let's say we are drawing 3 lines to resemble a capital letter A.

 

I've got the two sides drawn and want to draw the horizontal line from a "nearest" point of one side to what would be the intersection of the line I am drawing and the other side.

 

In real life we would use this to draw roof joists between hips and valleys.

 

I seem to recall being able to start drawing a line and getting a dashed tracking kind of line that would snap to the intersection ahead of where you're going.

 

Thanks!

Randy
