Question
A circle with center đ¶ which passes through the point đ is shown in the given figure.Which of the following best describes how to construct a line that is tangent to the circle at the point đ using a straightedge and compass?ResponsesConstruct a vertical line passing through point đ.Answer A: Construct a vertical line passing through point P .AConstruct a horizontal line passing through point đ.Answer B: Construct a horizontal line passing through point P .BConstruct a line passing through point đ¶ that is perpendicular to the line containing points đ¶ and đ.Answer C: Construct a line passing through point C that is perpendicular to the line containing points C and P .CConstruct a line passing through point đ that is perpendicular to the line containing points đ¶ and đ.
Solution
Para construir una lĂnea tangente al cĂrculo en el punto đ usando una regla y un compĂĄs, sigue estos pasos:
- Dibuja una lĂnea que pase por el centro đ¶ y el punto đ. Esta lĂnea es el radio del cĂrculo.
- Utilizando el compĂĄs, traza un arco con centro en đ y radio igual a la distancia entre đ y đ¶.
- Marca el punto donde el arco intersecta la lĂnea que pasa por đ¶ y đ. LlĂĄmalo punto đ·.
- Con el compĂĄs, traza un arco con centro en đ· y radio igual a la distancia entre đ· y đ.
- Marca el punto donde este nuevo arco intersecta el cĂrculo. LlĂĄmalo punto đž.
- Dibuja una lĂnea que pase por los puntos đ y đž. Esta lĂnea es perpendicular a la lĂnea que contiene los puntos đ¶ y đ.
Por lo tanto, la respuesta correcta es:
Construir una lĂnea que pase por el punto đ y que sea perpendicular a la lĂnea que contiene los puntos đ¶ y đ.
