Described below are the first two steps for constructing a parallel line through a point. 1. start with a line pq and a point r off the line. 2. draw a transverse line through r and across the line pq at an angle, forming the point j where it intersects the line pq. what is the exact angle required in step 2? a) 45° angle b) 60° angle c) 90° angle d) no exact angle
