Triangle for a popover (Photoshop)

Question

I am currently making a popover in Photoshop. I managed to do the main part using the rounded rectangular tool but not the triangle part:

Is there a recommend way in Photoshop to do this triangle ?

EDIT

I have seen this post which is the closest to what i want but :

1. I don't want round corner
2. I want a stroke on the triangle but not on the basis

Answer 1

Use the pen tool to add 3 anchors to the rounded rectangle path. Then use the Direct Selection Tool (the white arrow) to pull out the middle anchor.
