Answer and Step-by-step explanation:
Same side interior angles are angles that are on the same side of a transversal
Please find the diagram attached
Same side interior angles are also in the interior of the parallel lines where they form their angles(as is seen in the diagram attached)
Angle a for instance is an interior angle pairing with angle b along the transversal l. Angle t is an interior angle pairing with angle z along the transversal l
Sum of interior angles cut by a tranversal here is supplementary and therefore add up to 180 degrees such that angle a + angle b is 180 degrees like wise angle t + angle z =180 degrees
Same side interior angles in Parallel lines are supplementary if cut by a transversal
