If I understand the convoluted question correctly, the answer is supplementary angles.
Supplementary angles add up to 180 degrees
If the sum of two angles is 180° then they are called supplementary angles.
Straight line, or 2 angles that add up to 180 degrees are called supplementary angles.
They are then complementary angles
The angles that are equal to 180 are called supplementary angles. The angles that equal 90 degrees are called complimentary.
In a triangle, the sum of the measures of the angles is 180 degrees.
Supplementary angles add up to 180 degrees
If the sum of two angles is 180° then they are called supplementary angles.
They are called complementry angles
Straight line, or 2 angles that add up to 180 degrees are called supplementary angles.
They are supplementary angles that add up to 180 degrees
They are then complementary angles
The angles that are equal to 180 are called supplementary angles. The angles that equal 90 degrees are called complimentary.
SUPPLEMENTARY ANGLES are two angles the sum of whose measures is 180 degrees.
How can a circle measure 180 degrees? Circles don't have any angles!
The angles are called obtuse.Another Answer:Angles from 180 degrees to 360 degrees are reflex angles
An angle that measures more than 90 degrees but less than 180 degrees is called an "obtuse" angle. Note Angles less than 90 degrees are called "acute" angles. An angle that is exactly 90 degrees is called a "right" angle. Angles that are more than 90 degrees but less than 180 degrees are call "obtuse" angles. An angle that is exactly 180 degrees is called a "straight line". Angles that are more than 180 degrees and less than 360 degrees are called "reflex" angles.
