two straight angles
No. Supplementary angles are angles that add up to 180˚. One straight angle already equals 180˚. Two straight angles add up to 360˚.

No. Supplementary angles are angles that add up to 180˚. One straight angle already equals 180˚. Two straight angles add up to 360˚.
Two angles are called suplementary angles if they form a straight angle, that is to say 180 degrees.

Supplementary angles
They are supplementary angles.
The parallel postulate: "That, if a straight line falling on two straight lines make the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which are the angles less than the two right angles."
If a straight line falling on two straight linesmakes the interior angles on the same side of it taken together less than two right angles , then the two straight lines , if produced indefinitely , meet on that side on which the sum of angles is less than two right angles.
