Answer:

A. Triangle sum theorem.

Step-by-step explanation:

We have been given that $m\angle 1+m\angle 2+m\angle 3=180^{\circ}$ .

We know that angle sum property of triangle states that three angles of a triangle add up-to 180 degrees.

Since the sum of angles of a triangle is 180 degrees, therefore, option A is the correct choice.
