Corresponding Angles. When two lines are crossed by another line (called the Transversal): The anglesin matching corners are called Corresponding Angles.
Alternate Interior Angles. When two lines are crossed by another line (called the Transversal): The pairs of angles on opposite sides of the transversal but inside the two lines are called Alternate InteriorAngles.
Alternate Exterior Angles. When two lines are crossed by another line (called the Transversal): The pairs of angles on opposite sides of the transversal but outside the two lines are called Alternate Exterior
Consecutive Interior Angles. When two lines are crossed by another line (called the Transversal): The pairs of angles on one side of the transversal but inside the two lines are called Consecutive InteriorAngles
