Strictly speaking, the bisector is a ray that divides the angle in half and has a beginning at the same point where it starts and the rays forming the sides of this angle. However, with regard to the triangle under the bisector of the mean beam An angle bisector of a triangle is a straight line through a vertex which cuts the corresponding angle in half.Using Herons formula Edit. The shape of the triangle is determined by the lengths of the sides alone. The bisector of a right triangle. In order to know how to be a bisectorin a right- angled triangle, one must also use formulas. Do not forget that in a right- angled triangle, one corner is necessarily a straight line, i.e. equal to 90 degrees. Answer: As you can see in the picture below, the angle bisector theorem states that the angle bisector, like segment AD in the picture below, divides the sides of the a triangle proportionally.
