Angle Relationships

Vocabulary flashcards defining geometric angle relationships and their properties when lines are intersected by a transversal.

Vertical angles

Angles opposite each other at the same intersection, which are equal in measure.

Linear pair

Angles that are side by side, forming a straight line, which add to $180^\circ$.

Corresponding

Angles that occupy the same position at two intersections, which are equal in measure.

Alternate interior

Angles located between the two lines on opposite sides of the transversal, which are equal in measure.

Alternate exterior

Angles located outside the two lines on opposite sides of the transversal, which are equal in measure.

Consecutive interior

Angles located between the two lines on the same side of the transversal, which add to $180^\circ$.
