The sum of the measures of the three exterior angles (one for each vertex) of any triangle is 360 degrees. a segment drawn from a vertex and perpendicular to the opposite side, or to the side containing the opposite side. You may have guessed that exterior angles are on the outside of a triangle, but it's a little more specific than just that.An exterior angle must form a linear pair with an interior angle.This means that the exterior angle must be adjacent to an interior angle (right next to it - they must share a side) and the interior and exterior angles form a straight line (180 degrees). 2. The both interior opposite angles measure the same so it will be 2x. One interior angle of a triangle has a measure that is equal to the sum of the measures of the other two angles of the triangle. An interior angle is an angle inside the shape. ... A corollary to the Triangle Sum Theorem states that the measure of each angle of an equilateral triangle. In Euclidean geometry, the measures of the interior angles of a triangle add up to π radians, 180°, or 1 / 2 turn; the measures of the interior angles of a simple convex quadrilateral add up to 2 π radians, 360°, or 1 turn.
