two straight 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.
Supplementary angles
The angles of a semi-circle are on a straight line and angles on a straight line add up to 180 degrees.
Two angles are called suplementary angles if they form a straight angle, that is to say 180 degrees.
Any two angles who's measures add up to 180 degrees form a straight angle.

2 supplementary adjacent angles for a straight angle.
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
