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

What is the fifth postulate of Euclid's?
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."
What does Euclid's 5th postulate say?
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.
What has two angles with 180?
