Circle Geometry Conjecture: a mathematical statement that appears likely to be true, based on your observations, but has not been proven

The measure of a central angle equals the measure of its corresponding minor arc

The measure of a central angle is 360o minus the measure of the major arc with the same endpoints as the central angle

The measure of an inscribed angle in a circle equals half of the measurement of the arc it intercepts (or the central angle) central angle inscribed angle

All inscribed angles that intercept the same arc will have the same measurement arc CB

If an inscribed angle intercepts a semicircle, then it has a measure of 90o
