They would only form a straight line if they added to 180 degrees
Supplementary angles
two, since a right angle is 90o & a straight line is 180o
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.
straight line indicates 180o
An angle comprises two straight line segments or rays together with the point at which they meet.
No because then it would be a straight line not an angle
Yes because angles on a straight line add up to 180 degrees
acute,obtuse,right angle, and straight line. * * * * * Rather than straight line I would have said a reflex angle.
All The Angles On A Straight Line Add Up To 180 Degrees.
A straight line in angles represents 180 degrees.
A straight angle is an angle that measures 180 degrees and is drawn as a straight line. A straight angle is composed of two right angles whose measures are 90 degrees each.
