By a straight angle I assume you mean an 180° angle, so two angles that form a 180° angle would be called supplementary angles.
Complementary
Right angles aren't formed by other angles - it is already an angle itself. However, if you bisect a right angle, it becomes two acute angles.
if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
Perpendicular.
Two angles are called suplementary angles if they form a straight angle, that is to say 180 degrees.
By a straight angle I assume you mean an 180° angle, so two angles that form a 180° angle would be called supplementary angles.
Any two angles who's measures add up to 180 degrees form a straight angle.
Complimentary angles
Complementary and form a right angle
Complementary
A linear pair would be two angles that form a straight angle of 180 degrees.
If the noncommon sides of two adjacent angles form a right angle, then the angles are complementary angles.
i believe that's the definition! =)Angle BisectorAn angle is formed by two rays with a common endpoint. The angle bisector is a ray or line segment that bisects the angle, creating two congruent angles.
Intersecting two perpendicular lines will form right angles.
are said to be complementary
