In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, "eight angles") is a polygon that has eight sides. A regular octagon is represented by the Schläfli symbol {8}.
A regular octagon is a closed figure with sides of the same length and internal angles of the same size. It has eight lines of reflective symmetry and rotational symmetry of order 8. The internal angle at each vertex of a regular octagon is 135° and the sum of all the internal angles is 1080° (as for any octagon). The area of a regular octagon of side length a is given by
In terms of R (circumradius), the area is
In terms of r (inradius), the area is
These last two coefficients bracket the value of pi, the area of the unit circle.
The area can also be derived as follows:
where S is the span of the octagon, or the second shortest diagonal; and a is the length of one of the sides, or bases. This is easily proven if one takes an octagon, draws a square around the outside (making sure that four of the eight sides touch the four sides of the square) and then taking the corner triangles (these are 45–45–90 triangles) and placing them with right angles pointed inward, forming a square. The edges of this square are each the length of the base.
Thomas Jacob "Jack" Black (born August 28, 1969) is an American comedian, actor and musician. He makes up one half of the comedy and satirical rock duo Tenacious D. The group has three albums as well as a television series and a film. His acting career is extensive, starring primarily as bumbling, cocky, but internally self-conscious outsiders in comedy films. He was a member of the Frat Pack, a group of comedians who have appeared together in several Hollywood films, and has been nominated for a Golden Globe award. He has also won an MTV Movie Award, and a Nickelodeon Kids Choice Award as well as hosting the 2006, 2008, and 2011 Kids Choice Awards.
Black was born in Santa Monica, California, the son of two satellite engineers, Judith (née Cohen), who worked on the Hubble Space Telescope, and Thomas William Black. His mother is Jewish and his father converted to Judaism (Black attended Hebrew school). On The Tonight Show, he said his surname may have come from the occupational name Blacksmith. Black's parents divorced when he was 10; Black moved to Culver City with his father and frequently visited his mother’s home. As a child, Black appeared in a commercial for the Activision game Pitfall! in 1982, which was later shown during an appearance on Jimmy Kimmel Live and again on The Tonight Show with Conan O' Brien. When Black entered high school, his parents enrolled him at the Poseidon School, a private secondary school engineered specifically for students struggling in the traditional school system. Black also attended the Crossroads School, where he excelled in drama. He later attended UCLA but dropped out during his sophomore year to pursue a career in entertainment, at which point his father discontinued his financial support.[citation needed] Fellow UCLA alumnus Tim Robbins later cast Black in Bob Roberts. He also had recurring roles on the HBO sketch comedy series Mr. Show.
Jorge Guzmán Rodríguez (born August 2, 1963), better known as El Hijo del Santo ("The Son of the Saint"), is a Mexican professional wrestler, political activist and one of the most successful stars in Lucha Libre. He is the youngest son of the legendary professional wrestler, film actor and Mexican folk hero El Santo.
"Santito", as he is often called, was the only one of his father's 10 children to become a professional wrestler. He began wrestling without his father's consent in February 1982 as "El Korak" but he made his official debut as "El Hijo del Santo" in October of that year after he earned his college degree in Communication Science per his father's request. He shared his father's look, the silver mask, tights and cape, and moves but he was shorter and, although he would never become the same cultural icon, he would become a better in-ring performer than his father.
Early in his career, he was wrestled mainly for World Wrestling Association (WWA) (The Tijuana circuit) and Universal Wrestling Association (UWA) (a promotion that worked in the Mexico City area) but he did make his debut for Empressa Mexicana de Lucha Libre (EMLL) the promotion that later became Consejo Mundial de Lucha Libre (CMLL) in Arena Mexico in the summer of 1983. He also was voted "Rookie of the Year" in Mexico.
