Same Side Interior Angles

Same side interior angles are a pair of angles that are located inside the two parallel lines and on the same side of the transversal line that intersects them

Same side interior angles are a pair of angles that are located inside the two parallel lines and on the same side of the transversal line that intersects them. In other words, they are angles that are on the interior of the two parallel lines and are on the same side of the transversal.

For example, consider two parallel lines, line m and line n, intersected by a transversal line, line t. If angle A and angle D are both on the interior of line m and line n, and they are on the same side of line t, then they are considered same side interior angles.

Same side interior angles have a specific property called the same side interior angles theorem. According to this theorem, the sum of the measures of same side interior angles formed by a transversal intersecting two parallel lines is always equal to 180 degrees. In other words, if we denote the measure of angle A as x degrees and the measure of angle D as y degrees, then x + y = 180 degrees.

It is important to note that same side interior angles are different from other types of angles formed by a transversal intersecting two parallel lines, such as corresponding angles, alternate interior angles, and alternate exterior angles. Each of these types of angles has their own specific characteristics and properties that can be studied and used in various geometric proofs and mathematical calculations.
