1. Two angles that are supplementary are never complementary.
2. Angles with a common side and a common vertex sometimes form a linear pair.
3. Two angles that are vertical are never adjacent.
Complementary Angles
When two angles add up to form a right angle or [tex]90^\circ[/tex] angle, the angle is said to be a complementary angle.
Supplementary Angles
When two angles add up to form a straight line or [tex]180^\circ[/tex] angle, the angle is said to be a supplementary angle.
Adjacent Angle
Two angles are said to be adjacent if they have a common vertex and a common side.
Vertical Angles
Two angles are said to be adjacent if they have a common vertex but does not have a common side.
They are vertically opposite angles.
Thus,
- A complementary angle cannot be a supplementary angle.
- A linear pair have a common vertex and a common line or side.
- Vertically opposite angles cannot be adjacent angle.
