Alternate interior angles are pairs of angles located on opposite sides of a transversal, but inside the parallel lines. These angles are also equal, provided that the lines are parallel.

Alternate exterior angles are pairs of angles located on opposite sides of a transversal, but outside the parallel lines. Like corresponding and alternate interior angles, alternate exterior angles are equal if the lines are parallel.

  • Parallel lines are two or more lines that extend infinitely in opposite directions and never intersect. To understand the relationship between parallel lines and angles, we need to explore the concept of complementary and supplementary angles. When two lines are parallel, corresponding angles are equal, and alternate interior angles are also equal. This leads to the idea of the transversal, which is a line that intersects two or more parallel lines, creating pairs of corresponding, alternate interior, and alternate exterior angles.
