Measure the distances from the point where the angle bisectors intersect to each of the three sides along the angle bisector. To do this you will need to find the point of intersection of each angle bisector and the corresponding opposite side. Manipulate your triangle by dragging any vertex or side. How are these distances related?
a) They are equal in a triangle with equal sides.
b) They are inversely proportional to the lengths of the sides of the triangle.
c) They are directly proportional to the lengths of the sides of the triangle.
d) They are always greater than the length of the corresponding side of the triangle.
