Supplementary angles.
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
Any angles A, B where A + B = 180 deg.
A linear pair would be two angles that form a straight angle of 180 degrees.
two, since a right angle is 90o & a straight line is 180o
When 2 or more angles add up to 180 degrees they are said to be supplementary. Supplementary angles only occur on straight lines, so if one angle is said to be 120 the other angle has to be 60 degrees in order to form a straight line and also to add the angles to 180 degrees
They are supplementary angles.
they form a straight line
Supplementary angles
a straight line
they are called supplementary angles. a straight line has 180 degrees each side and two adjacent angles forming 180 degrees are called supplementary angles.

two straight angles
Angles in the straight line
Any angles A, B where A + B = 180 deg.
a supplementary angle is one of the two angles that form 180 degrees or a straight line.
