Answer:Corresponding Angles: These are angles in the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, corresponding angles are equal.
Alternate Interior Angles: These are angles that are inside the parallel lines, and on opposite sides of the transversal. If the lines are parallel, alternate interior angles are equal.
Alternate Exterior Angles: These are angles that are outside the parallel lines, and on opposite sides of the transversal. If the lines are parallel, alternate exterior angles are equal.
Consecutive (or Co-Interior) Angles: These are angles that are on the same side of the transversal and inside the parallel lines. If the lines are parallel, consecutive angles add up to 180 degrees (they are supplementary).
