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
