Construction To Bisect A Given Angle
An angle bisector is a line that divides an angle into two equal parts. Let's go through the steps to construct the bisector of a given angle.

Steps of Construction:
Step 1: Draw an Arc from the Vertex
Place the compass pointer at O (the vertex of the given angle ∠MON).
Draw an arc that intersects the two arms (OM and ON) at P and Q.
Step 2: Draw an Arc from One Intersection Point
Without changing the compass width much, place the compass pointer at P.
Draw an arc inside ∠MON.
Step 3: Draw Another Arc from the Other Intersection Point
Without changing the compass width, place the compass pointer at Q.
Draw another arc inside the angle, making sure it intersects the arc from P at a point Z.
Step 4: Draw the Angle Bisector
Use a ruler to draw a straight line from O to Z.
OZ is the required angle bisector of ∠MON.
Since ∠MOZ = ∠ZON, the angle has been perfectly bisected.
