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.
Any two angles who's measures add up to 180 degrees form a straight angle.
Complimentary angles
Complementary and form a right angle
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.
a supplementary angle is one of the two angles that form 180 degrees or a straight line.
No. For example, say the two angles are 10° and 20°. Then the other angle is 180°-10°-20°=150° and that is not a right angle. But if the triangle has two equal acute angles of 45 degrees then the 3rd angle must be 90 degrees which will form a right angle triangle.
The complementary angles form a right angle with the shared ray.
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.
