In triangle ABC, points D and E are the midpoints of sides AB and BC, respectively. If ED = k * AC, then what is the value of k

Since, according to the condition, points E and D are the midpoints of the sides BC and AB, then the segment ED is the middle line of the triangle ABC.

The length of the midline of a triangle is half the length of the side parallel to it.

ED = AC / 2 = AC * (1/2).

Then k = 1/2.

Answer: The value of the coefficient k is 1/2.
