What does tvis mean ? Also what language is this ?
A Telecommunications device for the deaf (TDD) is a teleprinter, an electronic device for text communication over a telephone line, that is designed for use by persons with hearing or speech difficulties. Other names for the device include teletypewriter (TTY), textphone (common in Europe), and minicom (United Kingdom).
The typical TDD is a device about the size of a typewriter or laptop computer with a QWERTY keyboard and small screen that uses an LED, LCD, or VFD screen to display typed text electronically. In addition, TDDs commonly have a small spool of paper on which text is also printed — old versions of the device had only a printer and no screen. The text is transmitted live, via a telephone line, to a compatible device, i.e. one that uses a similar communication protocol.
Explanation:
Un triángulo oblicuo es cualquier triángulo que no sea un triángulo rectángulo. Podría ser un triángulo agudo (los tres ángulos del triángulo son menores que los ángulos rectos) o podría ser un triángulo obtuso (uno de los tres ángulos es mayor que un ángulo recto). En realidad, a los efectos de la trigonometría, la clase de "triángulos oblicuos" también podría incluir triángulos rectángulos. Entonces, el estudio de los triángulos oblicuos es realmente el estudio de todos los triángulos.
