How to draw an angle bisector

Rahul Sil · Accepted Answer

Dear Student, Start with angle PQR that we will bisect Geometry construction with compass and straightedge or ruler or ruler

1 Place the compass point on the angle'svertex Q Geometry construction with compass and straightedge or ruler or ruler

2 Adjust the compass to a medium wide setting The exact width is not important Geometry construction with compass and straightedge or ruler or ruler

3 Without changing the compass width, draw an arc across each leg of the angle Geometry construction with compass and straightedge or ruler or ruler

4 The compass width can be changed here if desired Recommended: leave it the same Geometry construction with compass and straightedge or ruler or ruler

5 Place the compass on the point where one arc crosses a leg and draw an arc in theinterior of the angle Geometry construction with compass and straightedge or ruler or ruler

6 Without changing the compass setting repeat for the other leg so that the two arcs cross Geometry construction with compass and straightedge or ruler or ruler

7 Using a straightedge or ruler, draw a line from the vertex to the point where the arcs cross Geometry construction with compass and straightedge or ruler or ruler

Done This is the bisector of the angle ∠PQR Regards, Geometry construction with compass and straightedge or ruler or ruler

Start with angle PQR that we will bisect.
1. Place the compass point on the angle'svertex Q.
2. Adjust the compass to a medium wide setting. The exact width is not important.
3. Without changing the compass width, draw an arc across each leg of the angle.
4. The compass width can be changed here if desired. Recommended: leave it the same.
5. Place the compass on the point where one arc crosses a leg and draw an arc in theinterior of the angle.
6. Without changing the compass setting repeat for the other leg so that the two arcs cross.
7. Using a straightedge or ruler, draw a line from the vertex to the point where the arcs cross
Done. This is the bisector of the angle ∠PQR. Regards,
