Angle Relationships Geometry 1.5 Adjacent Angles • Two angles which share a vertex and a side, and nothing else. Complementary Angles • Two angles which add up to 90°; they are both acute. Supplementary Angles • Two angles which add up to 180°; either they are both right angles, or one is acute and the other is obtuse. Linear Pair • Two adjacent supplementary angles: They form a straight angle (line). Linear Pair • Two adjacent supplementary angles: They form a straight angle (line). Linear Pair • Two adjacent supplementary angles: They form a straight angle (line). Linear Pair • Two adjacent supplementary angles: They form a straight angle (line). Vertical Angles • Two angles on opposite sides of intersecting lines; they are always congruent. Vertical Angles • Two angles on opposite sides of intersecting lines; they are always congruent.
