# same side exterior angles

Are, Learn A polygon has exactly one internal angle per vertex. If every internal angle of a simple polygon is less than 180°, the polygon is called convex. The sum of all the internal angles of a simple polygon is 180(. How to solve for x using Alternate Interior Angles? ∠5 and ∠8 form a straight line. Corresponding Angles: The name does not clearly describe the "location" of these angles. For a simple (non-self-intersecting) polygon, regardless of whether it is convex or non-convex, this angle is called an interior angle (or internal angle) if a point within the angle is in the interior of the polygon. Make a conjecture about the relationship of the measures of the highlighted angles. In illustration one of the example section above, LINE 1 and LINE 2 are parallel and both interior and exterior angles on the same side of the transversal are supplementary. website builder. Q. Identifying Interior and Exterior Angles. Given two parallel lines are cut by a transversal, their same side exterior angles are congruent. The sum of the internal angle and the external angle on the same vertex is 180°. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary. If lines are parallel, then same side interior angles are supplementary and same side exterior angles are supplementary. We Reasoning, Diagonals, Angles and Parallel Lines, Univ. Based on the diagram above, the inside is referred to those angles located between lines a and line b So, what angles are inside and located on the same side? According to the theorem, they are supplementary, meaning that their angles add up to 180 degrees. Example 1: Using the parallel line conjectures, missing angle measures h= n= find the n a= So angle 2 and angle 7 are also supplementary same thing with angle 1 and angle 8.
