Acute and obtuse triangles Acute and obtuse triangles An acute triangle is a triangle with all three angles acute (less than 90°). An obtuse triangle is one with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180°, no triangle can have more than one obtuse angle. Acute and obtuse triangles are the two different types of oblique triangles—triangles that are not right triangles because they have no 90° angle. In all triangles, the centroid—the intersection of the medians, each of which connects a vertex with the midpoint of the opposite side—and the incenter—the center of
Many-angled ones Many-angled ones The many-angled ones are fictional other-dimensional beings linked to the Cthulhu Mythos. They first appeared in Grant Morrison's story "Zenith", which appeared in the British comics anthology "2000 AD". In "Zenith", they are known as the Lloigor, a direct reference to creatures from the Cthulhu Mythos. However, they appear somewhat different from the Cthulhu Mythos entities. In the comic, the many-angled ones plan to impose rigid geometrical order on the whole universe, essentially reducing it to clockwork. The many-angled ones exist in a space with more dimensions than our own; hence, they appear to be "many angled". As
