What Is The Difference Between Same Side Interior Angles And Same Side Exterior Angles. Look at the blue lines demonstrating the shape - the Z may be back to front as in the second example but the principle is the same. And are same side interior angles.
Same Side Interior Angles Theorem. The same side interior angles are the angles inside the parallel lines on the same side of the transversal and the same side exterior angles are the angles outside the parallel lines on the same side of the transversal. Then y 180 - x 180 - 115 65.
One of corresponding angles is always interior in between parallel lines and another - exterior outside of the area in between parallel lines.
On parallel lines alternate or Z angles are equal. Same Side Interior Angles Theorem. It means that the sum of two interior angles which are on the same side of transversal is supplementary. Their sum is 180 degs.
