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.

Can the angle bisector of a triangle also be the perpendicular bisector?
Yes. The bisector of one angle of a triangle is the perpendicular bisector of theopposite side if the bisected angle is the vertex angle of an isosceles triangle,or any angle of an equilateral triangle.
Can an angle have more than one bisector?
Since a bisector splits an angle into two congruent angles, it goes directly down the center. Therefore there can only be one bisector for any given angle.
If a point is equidistant from the two sides of an angle then it is?
on the perpendicular bisector
Is there a exactly one angle bisector in every angle?
Yes
What divides an angle into 2 congruent angles?
An Angle Bisector
