A transversal line cuts through parallel lines forming equal corresponding angles
Parallel lines can have a line crossing both of them. They call that the transversal. Corresponding angles are on the same side of the transversal. Alternate are on opposite sides of the transversal.
Alternate Exterior Angles :)
They are equal alternate angles
corresponding angles
They are angles formed by the transversal line cutting through parallel lines
When a transversal line cuts through parallel lines various angles are created such as equal corresponding angles and equal alternate angles as well as other types of angles.
Alternate Interior Angles
When parallel lines are cut through by a transversal line the alternate angles are equal
Corresponding and alternate angles
16 angles, 8 of each measure - unless the transversal is perpendicular in which case, all 16 angles are right angles.
Providing that the lines are parallel that the transversal passes through then it will have two equal alternate angles that are on opposite sides of the transversal.
