Multiple Choice: Jamila has started to construct a line parallel to line through point at right. Which of the possible strategies below make the most sense to help her find the line parallel to through point ?  

  1. Measure with a protractor.

  2. Use the compass to measure the arc centered at , then place the point of the compass where the arc centered at meets , and mark that measure off on the arc.

  4. Measure with a ruler.

A line going through points, Q and P is intersected by the line m at P. There is a point R on line, m, at the right of P. Angle R, P, Q, is marked as well as the straight angle about Q.

Drawing a line parallel to through point would create a corresponding angle congruent to .
