For any triangle, the rule is true: the sum of the interior angles of a triangle is 180 degrees.
But one more rule is fulfilled for this task for an isosceles triangle: the angles at the base in an isosceles triangle are equal to each other.
Hence, the angle at the apex of the triangle is calculated as follows:
180 – 44 – 44 = 92 (degrees).
