The exterior angle of a triangle is the angle formed by one side and the adjacent extended side of the triangle. There are three exterior angles in a triangle, and the sum of the exterior angles of a triangle is always equal. The Exterior Angle Theorem states that an exterior angle of a triangle is equal to the sum of its remote interior angles.
In a triangle, each exterior angle has two remote interior angles. The sum of the measures of the interior angles and the exterior angles of a dodecagon is equal to the sum of the measures of the two opposite interior angles of the triangle. Every triangle has six exterior angles, two at each vertex. An exterior angle of a triangle measures 125°, and one of the remote interior angles measures 35°. The triangle must be right.
There are six total exterior angles in a triangle, with two at each vertex. The Vertical Angles Theorem states that there are two exterior angles at each vertex, which are congruent by the Vertical Angles Theorem. Since there are three vertices, there are a total of 6 exterior angles.
A triangle is a 3 sided polygon, a clouded figure, and has 3 interior angles that always add to 180°. To find the missing measure, use a capital or lowercase letter in the equation.
