Answer» Answer: Step-by-step explanation: Argument Reason 1 Line SEGMENTS AB, PB, PA are congruent All drawn with the same compass width. 2 Triangle APB is an equilateral triangle Equilateral triangles are those with all three SIDES the same length. 3 Angle APB has a measure of 60° All three interior angles of an equilateral triangle have a measure of 60°. See Equilateral triangle definition Step 1: Draw the arm PA. Step 2: PLACE the point of the compass at P and draw an arc that cuts the arm at Q. Step 3: Place the point of the compass at Q and draw an arc of radius PQ that cuts the arc drawn in Step 2 at R. Step 4: With the point of the compass at R, draw an arc of radius PQ to cut the arc drawn in Step 2 at S. Step 5: With the point of the compass still at R, draw ANOTHER arc of radius PQ near T as shown. Step 6: With the point of the compass at S, draw an arc of radius PQ to cut the arc drawn in step 5 at T. Step 7: Join T to P. The angle APT is 90º. |
