Equilateral pentagon of δ can be seen from the figure: Simplifying, δ is obtained as function of α and β: The remaining angles of the pentagon can be found geometrically: The remaining angles of the orange and blue triangles are readily found by noting that two angles of an isosceles triangle are equal while all three angles sum to 180°. Then formula_7 and the two remaining angles of the green triangle can be found from four equations stating that the sum of the angles of the pentagon is 540°, the sum of the angles of the green triangle is 180°, the angle
Kings of the Angles Like Offa, Freawine is made a descendant of Woden, and father of Wig, whose names were intruded into the pedigree of the kings of Bernicia when it was transferred to that of the kings of Wessex (ancestors of the kings of England). Wihtlæg, Wermund and Offa also appear in a long list of legendary Danish kings given by Saxo Grammaticus ("Gesta Danorum"). All other sources name them as kings of the Angles, though according to Matthew Paris ("Vitae duorum Offarum") Offa and his line personally ruled over the West Angles, implying that other branches of the tribe had their own
