41+ Exterior Angle Inequality Theorem
Pictures. This geometry video tutorial provides a basic introduction into the exterior angle inequality theorem. The exterior angle theorem is proposition 1.16 in euclid's elements, which states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles.
Those will be the two basic types of questions that deal with the exterior angle theorem. State exterior angle inequality theorem; The content of this lesson focuses on the exterior angle inequality theorem and proofs on triangles.
Measures of interior angles of a triangle sum to 180°;
Using the triangle inequality theorem, you can write the following The exterior angle is formed when we extend a side of a polygon. Indicating that m r = m q. abc with c between a and d prove:
