Triangle Midsegment Theorem

• A midsegment has triangular symmetry in text parameters that could be discovered by varying the congruent letter patterns.

• A midsegment of a triangle is parallel to one side of the triangle, and its length is one half the length of that side.

• A midsegment is perpendicular to the third side of a triangle when the line divides the angles into two congruent angles.
