Study Notes

Special Angle Pairs in Geometry

Complementary Angles: Two angles with a sum of 90°.
Supplementary Angles: Two angles that add up to 180°.
Vertical Angles: Formed by the intersection of two lines; they are opposite angles and are equal.
Adjacent Angles: Share a common side and vertex without overlapping; for example, angles ABC and CBD share side CB and vertex B.
Linear Pair: Created when two intersecting lines form adjacent angles; together, they total 180°.
Corresponding Angles: Located at the same relative position at each intersection when two lines are crossed by another line; equal when the lines are parallel.
Alternate Interior Angles: Occur on opposite sides of a transversal crossing two lines; these angles are located inside the lines.
Alternate Exterior Angles: Formed on opposite sides of a transversal and outside the two intersected lines.
Same Side Interior Angles: When two parallel lines are cut by a transversal, these angles are supplementary, adding up to 180°.
Same Side Exterior Angles: Created when parallel lines are intersected by a transversal; located outside the parallel lines on the same side and are also supplementary.
