PQ is parallel to the plane ABC in its edge view. In that view, P is at a distance of 25 mm from ABC. |PQ| = 20 mm in the same view with Q oriented towards C. In the edge view of plane BCD, R is at 40 mm from the same plane and |RQ| = 15 mm. Find triangle PQR in all three views. Also, draw PQR in true shape. c1 d4 b1 b4 Name: _______________________________ Roll Number: _________________ BATCH: _________________
