The oche / ˈ ɒ k i /, also the throw line or toe line, in the game of darts is the line behind which the throwing player must stand. For steel tip darts, it is generally 7 ft 9 + 1 ⁄ 4 in (2.37 m) from the face of the dartboard, measured perpendicularly. This is the recognized world standard as set by the World Darts Federation and is used ...

Kites are also known as deltoids, [1] but the word deltoid may also refer to a deltoid curve, an unrelated geometric object sometimes studied in connection with quadrilaterals. [2] [3] A kite may also be called a dart, [4] particularly if it is ...
Since the dart can extend toward any edge of the pattern without affecting fit, the length of the dart intake at the edge of the fabric is not a good measure of dart intake. Rather, the angle subtracted from the pattern by the dart is what determines the dart's intake.
Length measurement, distance measurement, or range measurement (ranging) all refer to the many ways in which length, distance, or range can be measured. The most commonly used approaches are the rulers, followed by transit-time methods and the interferometer methods based upon the speed of light .
