Question

a student correctly uses a compass and a straightedge to draw line x, which is parallel to line w. the figure shows the final sketch. which point is most likely the last point the student constructs before drawing line x? point r point q point n point l

Explanation:

在使用圆规和直尺作平行线时，通常先在已知直线上取点构造等角等步骤，最后通过确定的对应点连线得到平行线。点R是确定平行线位置关键的最后构造点，通过它和其他点确定直线x的位置。

Answer:

A. point R
