The value of <u>ML = 3</u>, using the mid-point theorem of triangles.
According to the midpoint theorem, "the line segment of a triangle crossing the midpoints of two sides of the triangle is said to be parallel to its third side and also half the length of the third side."
In the question, we are given that triangle ABC is an equilateral triangle, and L, M, and N are the midpoints of BC, AB, and CA respectively.
Thus, by the midpoint theorem, we can say that:
- MN || BC, and MN = (1/2)BC,
- ML || AC, and ML = (1/2)AC, and
- NL || AB, and NL = (1/2)AB.
Assuming AB = BC = AC = x units, we get:
- MN = (1/2)BC = x/2,
- ML = (1/2)AC = x/2, and
- NL = (1/2)AB = x/2.
Thus, the triangle LMN is an equilateral triangle.
Thus, MN = ML = NL.
Given MN = 3, we can write the value of ML = 3.
Thus, the value of <u>ML = 3</u>, using the mid-point theorem of triangles.
