Relationship to Thales' Theorem. Refer to the above figure. If the two points A,B form a diameter of the circle, the inscribed angle will be 90Â°, which is Thales' Theorem. You can verify this yourself by solving the formula above using an arc length of half the circumference of the circle. You can also move the points A or B above until the inscribed angle is exactly 90Â°.
According to native Minnesotan Dr. John Spartz, the Minnesota accent is actually an Upper Midwest dialect that includes Minnesota, parts of North Dakota and South Dakota, northern Iowa and western Wisconsin.
Some cited guy named Frisch believes that the word actually comes from Latin nodulus which would be the adjective for 'knot, node', hence 'knotty'.
