    One.
  • Question
    How do I prove that the ray drawn bisects the angle?
    Community Answer
    Community Answer
    Check the angles between either of the original rays and the bisector line. If they are equal, then the line is the exact bisector.
  • Question
    How can I draw more than one angle bisector?

    Any given angle has exactly one bisector.
  • Question
    I learned it a different way. Is this the correct way for a test?

    Probably, but only your teacher knows for sure.
  • Question
    How do I draw a perpendicular bisector in a right angle?

    Community Answer
    A right angle does not have a perpendicular bisector. (Only a 180° angle has that.) A right angle can be bisected following the steps in the above article.

    What is angle bisector theorem in a triangle?
    Community Answer
    Community Answer
    When you bisect the angle of a triangle, it divides the opposite side into two line segments. The angle bisector theorem states that the relative size of these two line segments is proportional to the relative size of the other two sides of the triangle.
  • Question
    What is the angle bisector theorem?
    Community Answer
    Community Answer
    A bisector divides an angle into two equal parts. The theorem states whenever a perpendicular is drawn from the bisector to arms of the angle would have same length.
  • Question
    Why is the radius taken more than half while drawing the bisector of the angle?
    Donagan

    That technique increases the likelihood of an accurately drawn bisector.
  • Question
    When I draw the interior arc, do I draw it keeping the width of the compass the same as how I drew the first arc?

    No. While the two interior arcs must have the same radius, those radii do not have to be the same as the radius of the first arc drawn.
