A triangle has three exterior angles, and the sum of these angles is always equal to 360°. To find the exterior angle of a triangle, use various formulas depending on the other side of the triangle. An exterior angle is formed by extending one side of the triangle and the extension of an adjacent side. Every triangle has six exterior angles, two at each vertex. Angles 1 through 6 are exterior angles.
The exterior angle inequality theorem states that the measure of any exterior angle of a triangle is greater than each of the opposite interior angles. This theorem holds true for all six exterior angles of a triangle. The exterior angles of a triangle are the angles that form a linear pair with the interior angles by extending the sides of a triangle. The sum of the exterior angles of a triangle and any polygon is 360 degrees.
A triangle has three interior angles, and each exterior angle forms a linear pair with its corresponding interior angle. A triangle has six exterior angles, as it is considered as two pairs of exterior angles, with three exterior angles in each pair.
A regular triangle has a measure of 60 degrees, so each has an exterior angle of 120 degrees. Given three sides, this provides a total of 6 exterior angles. An exterior angle of a triangle is an angle formed by one side of the triangle and the extension of an adjacent side.
