rebuilding a steeple roof

[JCD]

For the builders out there, I'm trying to rebuild a steeple roof and I can't find a shape that matches.
I'm looking for a square block with a outer face of about 75 degrees definitely steeper than 60 degrees, I have gone through the menu and can't find anything that matches or is there a way to highlight a similar block and copy it?

If you enable creative mode, you can use the paintbrush (yes) to copy a block to your toolbelt (make sure you have a space for it).

Or, that steep or shallow angle could be the narrow wedge blocks. Search narrow in the shapes menu.
