Such is called an exterior angle. A useful theorem is that an exterior angle is equal to the sum of its non adjacent interior angles.
Yes, all plane triangle.
Yes, if you interpret some of the exterior angles as having negative measure.
360 divided (180-n) This uses the exterior angle theorem and linear pair theorem. This works on regular polygons. All the angles congruent.
exterior angle theorem
There is the Exterior Angle Inequality Theorem: If an angle is an exterior angle of a triangle, then its measure is greater than the measure of either of its corresponding remote interior angles.i don't know if that relly helps, but that's all i got
Theorem 6-1-2; Polygon Exterior Angle Sum Theorem:The sum of the exterior angle measures, one angle at each vertex, of a convex polygon is 360 degrees.
No, it does not.
no it dose not
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
Pairs of Alternate Exterior Angle are Congruent
For any polygon: 180-interior angle = exterior angle and the exterior angles of any polygon add up to 360 degrees
triangle sum theorem
the exterior angle theorem
Such is called an exterior angle. A useful theorem is that an exterior angle is equal to the sum of its non adjacent interior angles.
No matter how many sides a convex polygon has, the sum of its exterior angles is 360°.
