TermDefinitionExample
TransversalA line that intersects two or more coplanar lines at distinct points.In a diagram with lines 'm' and 'n', a third line 't' that crosses both 'm' and 'n' is the transversal.
Interior AnglesThe angles that lie in the region between the two lines being intersected by the transversal.If a transversal intersects two horizontal lines, the four angles located between those two lines are the interior angles.
Exterior AnglesThe angles that lie in the regions outside of the two lines being intersected by the transversal.If a transversal intersects two horizontal lines, the four angles located above the top line and below the bottom line are the exterior angles.
Corresponding AnglesA pair of angles that are in the sam...

Core Formulas
Checklist for Corresponding Angles
A pair of angles (\angle A, \angle B) are corresponding if: (1) One is an interior angle, (2) One is an exterior angle, (3) They are on the same side of the transversal, (4) They are not adjacent.
Use this checklist to verify if two angles are in the same 'corner' at each intersection.
Checklist for Alternate Interior Angles
A pair of angles (\angle A, \angle B) are alternate interior if: (1) Both are interior angles, (2) They are on opposite sides of the transversal, (3) They are not adjacent.
Use this checklist to find interior angles that are on opposite sides of the transversal.
Checklist for Consecutive Interior Angles
A pair of angles (\angle A, \angle B) are consecutive interior if: (1) Both are interior angles, (2) T...
