Provide an appropriate response.Use a compass and straightedge to construct the inscribed circle to the triangle shown below.
What will be an ideal response?
Answers will vary. A sample correct response would be as follows.
Construct the angle bisectors, say RX and QY to two of the three angles of the triangle PQR (you may construct all three, but two suffice). Let the point of intersection be O. Then the circle through O of radius OX (= OY) is the inscribed circle.
