Quarter Round: How to cut at unusual angles
If you do, the simplest way to measure the angles is to buy a bevel square.
A bevel square has an wing nut which allows the blade to move.
To use it, you loosen the wing nut, place the square against the corner you wish to measure, tighten the nut, then determine the overall angle in degrees by placing the square on your mitre saw table.
If, for example, you determine you have a 50 degree inside corner, you will then know you need to cut the two pieces of molding with 25 deg angles (25 +25 = 50). If you have a 37 degree angle, you will make two mitre cuts at 18.5 degrees and so on.
A bevel square sells in the US for about $5.

When I'm not certain how to make a corner cut, I place the "matching" two pieces of quarter round where they will be, and draw a pencil mark on each to show me how I need to cut using the mitre box and saw.
The pencil mark won't necessarily be at the precise angle or position of the cut - it just gives me a guide as to what cut to make, at what angle. (The mitre saw makes the angle right.)
Hope this helps you.
