Question

practice: topic - 1: constructions (mcqs)
a student is constructing a parallel line to line v through point q.
which step will the student complete next to continue the construction correctly?

Explanation:

Brief Explanations

在通过点Q构造与直线v平行的直线时,通常先在直线v上以某点为圆心画弧,与直线v相交,然后在点Q处以相同半径画弧。图中已完成在直线v上画弧和在点Q处画弧的初步步骤,下一步应是在直线v上的弧与直线v的交点处,以该交点为圆心,以两弧交点间的距离为半径画弧,与点Q处的弧相交,从而确定平行线上的点。观察选项,应选第三个图(从下往上数),它展示了在直线v上的弧的交点处画弧的操作。

Answer:

第三个图(从下往上数)
