Same Side Interior Angles
Interior angles that lie on the same side of the transversal. (3.1)
Same side interior angles are a pair of angles that are on the same side of a transversal line and are between two parallel lines. In other words, they are two angles that have one leg in common and are inside the parallel lines.
When two parallel lines are intersected by a transversal line, eight angles are formed. Among these angles, the same side interior angles are the two angles that are on the same side of the transversal and have a common interior point between the two parallel lines.
The sum of the same side interior angles is always equal to 180 degrees. In other words, if two same side interior angles are represented by x and y, then their sum is x+y= 180 degrees.
Same side interior angles can be used in many mathematical problems. For instance, if you are given some angles and asked to find the value of an unknown angle, you can use the concept of same side interior angles to determine the value. You can set the sum of the known same side interior angles equal to 180 degrees and then solve for the value of the unknown angle.
