Naomi draws a portion of a figure as shown. she wants to construct a line segment through r that makes the same angle with line segment qr as line segment pq. a line segment qr is drawn. pq is a line segment that makes an obtuse angle of about 120 degrees with qr. an arc, indicating the measure of angle pqr intersects pq at s and qr at t. another arc drawn from point r is a reflection of the first arc but of the same measure and intersects qr. which figure shows the next step to construct a congruent angle at r?
