METHOD 1:

Step 1: Measure the angles divided by the line segment at the vertex

NOTE: An angle bisector is a line or ray that divides an angle into two

congruent angles.

Step 2: Conclude that the line segment is angle bisector if the line segments divides the angle into to equal parts.

METHOD 2:

Step 3: Use the angle bisector theorem.

NOTE: An angle bisector of an angle of a triangle divides the opposite

side in two segments that are proportional to the other two sides of the

triangle.

Step 4: Conclude that the line segment is angle bisector if it satisfies the proportion
