# Constructing an Angle Bisector

How to construct an angle bisetor of the given angle.

## Goal

Goal:

Constructing the red ray

that bisects the given angle

## How to Construct

Place the point of the compass

at the vertex of the given angle.

(red point)

Draw an arc.

(red arc)

Place the point of the compass

at the intersection of the ray and the blue arc.

(red point)

Draw an arc that seems to pass

the middle of the angle.

(red arc)

Without changing the radius of the compass,

place the point of the compass

at the other intersecting point.

(red point)

Draw an arc (red arc)

that passes through the previous arc (blue arc).

Draw a ray that passes through the blue arcs.

(red ray)

Then the ray is the angle bisector of the given angle.
