Relationships between angles 2025 Geometry

Alternate interior

Alternate sides of the transversal inside the lines. Congruent.

Alternate exterior

Alternate sides of the transversal exterior/outside pair. Congruent.

corresponding

Same position, different vertexes. Congruent.

consecutive interior

(same-side) same side of the transversal inside pairs. Supplementary.

vertical

Angles formed by intersecting lines, opposite each other. Congruent.

Linear

angles that are adjacent and formed by two intersecting lines. They are supplementary.

supplementary

Angles that add up to 180 degrees, often formed by a linear pair.

congruent

Angles that have the same measure. They can be vertical angles or corresponding angles.
