|After doing this||Your work should look like this|
|Start with a angle BAC that we will copy.|
|1. Make a point P that will be the vertex of the new angle.|
2. From P, draw a ray PQ. This will become one side of the new angle.
|3. Place the compasses on point A, set to any convenient width.|
|4. Draw an arc across both sides of the angle, creating the points J and K as shown.|
|5. Without changing the compasses' width, place the compasses' point on P and draw a similar arc there, creating point M as shown.|
|6. Set the compasses on K and adjust its width to point J.|
|7. Without changing the compasses' width, move the compasses to M and draw an arc across the first one, creating point L where they cross.|
|8. Draw a ray PR from P through L and onwards a little further. The exact length is not important.|
|Done. The angle ∠RPQ is congruent (equal in measure) to angle ∠BAC.|
