Supplementary angles
a straight line
The angles of a semi-circle are on a straight line and angles on a straight line add up to 180 degrees.
A straight angle is an angle.

Supplementary angles
They would only form a straight line if they added to 180 degrees
Supplementary angles.
they form a straight line
They are supplementary angles.
Yes because angles on a straight line add up to 180 degrees
How many of these 30° angles will fit together to make a straight line?
a straight line
The angles of a semi-circle are on a straight line and angles on a straight line add up to 180 degrees.
A straight angle is an angle.
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 angles form a straight line since they add to 180 degrees by definition
