Equilateral triangle terms of side length "a" can be derived directly using the Pythagorean theorem or using trigonometry. The area of a triangle is half of one side "a" times the height "h" from that side: The legs of either right triangle formed by an altitude of the equilateral triangle are half of the base "a", and the hypotenuse is the side "a" of the equilateral triangle. The height of an equilateral triangle can be found using the Pythagorean theorem so that Substituting "h" into the area formula (1/2)"ah" gives the area formula for the equilateral triangle: Using trigonometry, the area of
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.
