44. How do you calculate the sum of the measure of the interior angles of a triangle?

1. (n+2)/180
2. (n-2)*180
3. (n+2)*180
4. (n*2)*180

Answer

The correct answer is: B) (n-2)*180

Explanation

The correct formula for calculating the sum of the internal angles of a triangle is:

Interior Angle Sum = (n - 2) * 180 degrees

Where "n" is the number of sides (or vertices) of the polygon, and "n" is 3 for a triangle.
