Geometry Angle Relationships Vocabulary

Vocabulary flashcards reviewing angle definitions and geometric relationships from lecture notes.

Alternate Interior Angles

Angles located between two lines on opposite sides of the transversal, which are congruent.

Alternate Exterior Angles

Angles located outside two lines on opposite sides of the transversal, which are congruent.

Consecutive Interior Angles

Same-side interior angles located inside two lines that are not equal and are supplementary, adding up to $180^\times$ or $180^\text{ degrees}$.

Adjacent Angles

Angles that are side-by-side and share a common vertex and a common side, with no common interior points.

Congruent Angles

Angles that are equal.

Complementary Angles

Angles whose sum adds up to $90^\text{ degrees}$.

Supplementary Angles

Angles whose sum adds up to $180^\text{ degrees}$.
