An obtuse and an acute angle together are the two angles together that form a straight line. However, together they must add up to 180 degrees.
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
two, since a right angle is 90o & a straight line is 180o
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
