Crazy Angle Cutting Question?

Why when I set my chop saw to cut a 50 degree angle, is the angle on the wood @ 40? If I set it to cut a 30 degree angle is the angle on the wood @ 60. The angle is always opposite but always totaling 90. Why does it not cut the angle I set it for, 60 cut 60. Or if I want a 60 degree cut do I and everyone out have to set the saw at 30? Everyone probably thinks I'm a nut and this is driving me nuts. :) Thanks once again for everyone's help.

Forget all those other angles, just set it to 45 and you'll never have those problems again

It all comes back to your point of reference. The fence is @180 degrees (straight line). The blade set @0 is actually @90degrees (perpendicular) to the reference of the fence. So when you set your saw to 30 degrees left, the 30 is actually measuring the angle between the right side of the blade and the "zero" reference mark (perpendicular to the 180 fence). What remains is its complementary angle of 60 degrees. Make any sense?

I think I just figured out how I'm going nuts! I'm looking at my cuts based on the horizontal axes and the saw is pulling its cuts off of the vertical axes. Am I right?
