Draw a perpendicular to that line and extend the arms of the angle to meed the perpendicular drawn earlier.
Check if the line is bisecting the perpendicular, if yes, then the line is a bisector of the angle.

What is an angle bisector?
An angle formed by two rays with a common endpoint. The angle bisector is a ray or line segment that bisects the angle, creating two congruent angles. To construct an angle bisector you need a compass and straightedge. Bisectors are very important in identifying corresponding parts of similar triangles and in solving proofs or simply a line which cuts an angle into two equal halves
An angle bisector is a with its endpoint on the vertex of the angle that divides the given angle in two parts?

What theorem is used to prove a segment is a bisector?
A segment need not be a bisector. No theorem can be used to prove something that may not be true!
When constructing the circumcenter and circumscribed circle of a triangle you need to find the intersection of all three of which type of line?
the perpendicular bisector
What angle do parallel lines make?
For two parallel line segments or rays to form an angle, they would either need to coincide with each other, forming a 0° or 360° angle, or they would need to be extending in opposite directions from their shared point, forming a 180° angle.
What is the angle bisector concurrency theorem?
the definition of an angle bisector is a line that divides an angle into two equal halves. So you need only invoke the definition to prove something is an angle bisector if you already know that the two angles are congruent.

Mid point of a segment and angle bisector?
Definition of angle bisector:An angle is formed by two rays with a common endpoint. The angle bisector is a ray or line segment that bisects the angle, creating two congruent angles. To construct an angle bisector you need a compass and straightedge.Definition of midpoint:Midpoint of a line segment is the point that is halfway between the endpoints of the line segment. A line segment has only one midpoint. If AB is a line segment and P is the midpoint, then AP = BP =

When constructing an angle bisector why must the arcs intersect?
The arcs must intersect because you need a point to use with the point of the angle's vertex to make the line that intersects the angle.
Does a line segment bisector always be perpendicular to the original irie?
Not sure what an "irie" is. But a bisector does not need to be perpendicular.
What is an angle bisector and how do you make one?
The angle bisector is a ray or line segment that bisects the angle, creating two congruent angles. To construct an angle bisector you need a compass and straightedge. Bisectors are very important in identifying corresponding parts of similar triangles and in solving proofs. Here's a helpful website recommended by my daughter's math teacher. It has a bunch of math video lessons with concept explanations and sample problems. The best part is, it is free. Hope this will help you too. http://www.brightstorm.com/d/math/s/geometry/u/constructions/t/constructing-an-angle-bisector
Write a two column proof for each of these problems given line ab is congruent to line ad and line ca is congruent to line ea prove angle abc is congruent to angle ade?
There cannot be a proof since the statement need not be true.
What are the proper steps for constructing an angle bisector?
Suppose you need to bisect angle PQR using only a pair of compasses and a straight edge:Draw an arc with the point of the compass at Q so the arc QP at X and QR at Y.Draw an arc with the point of the compass at X so that the arc is between the arms of the angle and extends to more than halfway across.Without changing the compass setting, draw an arc with the point of the compass at Y so that this arc intersects the previous arc at Z.Using the straight edge, draw the line QZ: this is the bisector of angle PQR.
