Why is a digital caliper held at a 45 degree angle

When using the gauge on your saw it is off on the 45 degree cut? If so you might have to use a tri Square every time you want to cut a 45. Sometimes the lock gauge for the 45 angle may be off some. When you put a tri square on the board you cut it is not a true 45 even though the saw says it is?

Make sure your rear derailleur is lined up with one of the rings of teeth on your rear gears( cassette ). Also make sure Your chain is riding correctly on one of the front gears on your crank. If you are still unable to back pedal make sure that one of the cogs (gears) in the rear derailleur arm isn't seized. They must both be able to rotate and the chain should pass through them in a backward S pattern. If you still can't back pedal remove the back wheel or move the chain off the cassette to see if the cassette will freewheel. It has to move freely in a counterclockwise direction in order for you to backpedal. Moving in a clockwise direction engages pawls inside the cassette which lock it into a drive situation which propels the bike. If the cassette will not freewheel in a counterclockwise direction you will need to take the rear wheel to a good bicycle shop to have the cassette replaced. It requires a special tool to remove it. Hope this helps.
