A quadrilateral
Supplementary Angles total 180o. A straight line is theoretically an angle of 180o. Draw a straight line (ruler) and draw another straight line from anywhere you like on it and at any angle you like. You have created a pair of supplementary angles!
A diagonal has no shape, it is a straight line between the angles of a multi-sided figure.
straight line indicates 180o
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 circle..

Angles in the straight line
A straight line has no right angles. But a square is actually a closed line with four right angles.
A straight angle is 180°, so if there is 180° between the first line and the second, and 180° between the second and the third, then the result is a straight line.
