In the diagram the angles are mentioned by the numbers. $∠\text{ }6,\text{ â¶Ä‰}∠\text{ }7,\text{ â¶Ä‰}∠\text{ }10,\text{ â¶Ä‰}∠\text{ }11$re interior angles and rest of them are exterior angles.

Alternate interior angles: These are the two nonadjacent interior angles which are on the opposite sides of the transversal.

Same-side interior angles: These are the two interior angles which are on the same sides of the transversal.

Corresponding angles: These are the two angles which relative to the two lines are in the corresponding position.

Consider the figure

It can be observed that pair of angles ($∠7$and $∠11$) and ($∠6$and $∠10$) are two pairs of interior angles which are on the same sides of the transversal.

Thus, by using the above definitions, it can be said that $∠7$and $∠11$are Same-side interior angles.
