To calculate the sum of the angles in a triangle, you can add the measures of the three angles together. The Triangle Angle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.

For example, if you have a triangle with angles measuring 30 degrees, 60 degrees, and 90 degrees, you can calculate the sum as follows:

30 degrees + 60 degrees + 90 degrees = 180 degrees

So, in this case, the sum of the angles in the triangle is 180 degrees, which confirms that it is a valid triangle.

In the example given, the angles measuring 30 degrees, 60 degrees, and 90 degrees all combine to equal 180 degrees, satisfying the Triangle Angle Sum Theorem.
