An interior angle is an angle defined by two sides of a polygon and that is inside the polygon. Opposite interior angles are specific pairs of interior angles, those that are opposite each other in the polygon. Alternate or opposite interior angles are also angles that lie on opposte sides of the tranversal line that cuts through parallel lines.

The term "diagonal" refers to a line segment that connects two non-adjacent vertices of a polygon or polyhedron. In geometry, diagonals are used to describe lines that cross through the interior of a shape, such as a rectangle or a square. For example, a rectangle has two diagonals that intersect at its center. Diagonal lines can also refer to orientations in graphs or coordinate systems that are not aligned with the axes.
