Answer 1

Answer:

  the rotation angle is double the angle between the lines

Step-by-step explanation:

The Reflections in Intersecting Lines Theorem will tell you that the effective angle of rotation is double the angle between the intersecting lines. Here, the figure is effectively rotated 144°, not 72°. If a 72° rotation is desired, the lines need to intersect at an angle of 36°.
