They would only form a straight line if they added to 180 degrees
two, since a right angle is 90o & a straight line is 180o
Supplementary angles
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
No because then it would be a straight line not an angle
An angle comprises two straight line segments or rays together with the point at which they meet.
acute,obtuse,right angle, and straight line. * * * * * Rather than straight line I would have said a reflex angle.
Yes because angles on a straight line add up to 180 degrees
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.
