3. Steve listed the steps he took when constructing a circumscribed circle of AABC.What is the missing step? I. Draw the perpendicular bisector of AB . I. II. Label the point of interception of the perpendicular bisectors R. IV. Use a compass to draw a circle with center R and radius RA. A. Repeat step 1 for BC or AC. B. Draw medians for each of the two triangles formed by the perpendicular bisector of AB. C. Draw a median of the triangle and label its base R. D. Label one of the midpoints of the triangle R.

5.) Two points A and B are on opposite sides of a building.  A surveyor selects a third point        C to place a transit.  Point C is 50 feet from point A and 68 feet from point B.  The angle ACB is  48°.  How far apart are points A and B? a.) REPRESENT this situation by drawing and labeling a picture.     b.) Solve for the distance between points A & B.  Round to the nearest foot.  COMMUNICATE by showing all of your work.

Put the steps below in the appropriate order to inscribe a regular quadrilateral in a circle. 1 Construct circle P. 2 Draw segments AB, BC, CD, and DA 3 Draw diameter AC. 4 Construct a perpendicular bisector of AC. 5 Label the intersections of the bisector and the circle as B and D. :::: :::: :::: :::: ::::
