Squares and triangles question
If I have a square and I want to put a triangles on each side how do I come up with the proper measurements for the triangle? Any help with this would be appreciated.

Jenny Doan has this in one of her u-tube tutes. What ever size of the square that you want to add triangles to, just say 61/2 in. For triangle color cut the same size square. Cut from corner to corner both ways making 4 triangles. Add to square and trim.

I resort to graph paper.
I draw the "finished size" of the square and triangle on graph paper - then add seam allowances to my drawings.
Then I measure my drawings - I would probably cut them out and glue them to template plastic.
One can cut the triangles one at a time, as half-square triangles, or as quarter-square triangles. "How" one cuts the triangles is determined by the fabric available, and how you want the grain lines on the finished item.
For the drawing on the bottom - and you want to cut the triangles as QSTs from a square -
The (theoretical) formula is:
Center square: finished size plus 1/2 inch
Square to cut QSTs from: finished size of side of center square plus 1-1/4 inches (I would cut them at least 1-3/8 inches)
Example: Center square finishes at 4 inches - cut square 4-1/2 inches
Triangles - cut square 5-1/4 inches to cut into QSTs (I would cut my square at least 5-3/8 inches and trim.)

Thank you Ladies this was a big help. I am trying to teach my sister how to quilt and I always use a pattern so when she ask me this question I didn't know. But now I will be able to help her and we both will be learning! Thank you all for your help!
