Help determining angles


I want to install a diagonal brace on my fence gate. I'm not very good at determining angles. The two corners that it will meet are 90 degrees inside. What type of tool or method can I use to to mark this on my brace?

If it's truly vertical why are there angles, are you putting in a cross brace?

You could always hold the board up to the gate and transpose some marks on it, then use a framing square to ensure a 90* cut based on your (2) outside marks.

I apologize - I meant a diagonal brace.

Is the gate built yet?

Can you post a photo of the gate? How it's cut and installed depends on the gate's conctruction. Sometimes you inset it into the frame, sometimes you attach it to the frame.
Sometimes you can use a turnbuckle with an adjustable nut to keep it square.

It will be inserted into the frame. I'll take a picture in the evening. I want to use a wooden brace in this situation as a turnbuckle will be unsightly with the style.

My assumption is the gate is a rectangle so a diagonal's angle would be 45 degrees to the horiz or vertical planes.

You might want to rethink that, your statement would only be true if the gate was square. The total of the (2) cuts will equal 90*, but it may be 50* and 40* cuts.

Is there a tool that can be inserted into the corner to determine the angle aside from just eyeballing, tracing, or calculating with math?

Easy to use a bevel guage and a protractor. Open the bevel guage to the 2 sides and transfere it to a piece of paper. Take the protractor and measue the angle.
If the frame of the gate is a rectangle, the brace will go corner to corner, so you would need to know the angle corner to corner and the distance between them to cut a snug brace.
Pull a line corner to corner and bevel guage the side to string angle(measure the alternate interior angles) on both sides(they should be the same). Then measure the distance, corner to corner.

If the math is uncertain for you then you could post the gate measurements here and many folks would provide the correct angles and lengths.

Just need the inside (where the brace is intended to fit) width, height and corner to corner.

I don't need the corner-to-corner...do you?
