Euler line the Euler line is parallel to an acute triangle's side "BC" if and only if formula_43 The locus of the centroids of equilateral triangles inscribed in a given triangle is formed by two lines perpendicular to the given triangle's Euler line. In a right triangle, the Euler line coincides with the median to the hypotenuse—that is, it goes through both the right-angled vertex and the midpoint of the side opposite that vertex. This is because the right triangle's orthocenter, the intersection of its altitudes, falls on the right-angled vertex while its circumcenter, the intersection of its perpendicular bisectors of sides,
The Price Is Right and his first episode airing on October 15. It is believed to be the longest-running game show on television (the Spanish-language variety show "Sábado Gigante" ended on September 19, 2015). It is also the longest running game show airing episodes five days-per-week in the world. "The Price Is Right" is one of two game show franchises (along with "To Tell the Truth") to be seen nationally in either first-run network or syndication airings in the U.S. in every decade from the 1950s onward.
