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.
two, since a right angle is 90o & a straight line is 180o
A linear pair would be two angles that form a straight angle of 180 degrees.
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 form a straight line
Supplementary angles
They are 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.
Supplementary
Two adjacent angles that have noncommon sides forming a line are called supplementary angles. This means that the two angles add up to 180 degrees. The noncommon sides of the angles create a straight line, demonstrating their supplementary relationship. An example of this would be a pair of angles that share a vertex and one side, with their other sides extending in opposite directions to form a straight line.
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
Two adjacent supplementary angles form a linear pair. This means that the two angles are next to each other and their measures add up to 180 degrees, resulting in a straight line. The shared side between the two angles is the line that connects them.
