QR passes through point S and is perpendicular to TU at S. Suppose QR is dilated by a scale factor of 1/3 centered on point S. Which of the following statements is true for the dilated lines?
1. The dilated line segments intersect at S but are not perpendicular
2. The dilated line segments intersect at a point other than S
3.The dilated lines are perpendicular
4. the dilated lines are parallel
1 answer
only the length of QR is changed, so it is still ⊥ to TU
