Angles are complimentary or supplementary. Lines aren't.
Then they would not be supplementary lines.
Perpendicular lines.
When Two parallel lines are cut by the transversal, __________ angles are supplementary
They are just straight lines that is a 90* angle.
Vertical angles can be supplementary angles if the lines are perpendicular and then both of the vertical angles would be 90 digress.
Alternate and supplementary
If the lines are perpindicular then each pair of vertical angles are supplementary
supplementary angles on parallel lines.
Supplementary contour lines are additional contour lines drawn between the main contour lines on a topographic map. They help to provide a more detailed representation of the elevation of the terrain and aid in visualizing the slope and features of the landscape more accurately.
They're supplementary
Yes. If two intersecting lines form the angles A, B, C and D (in rotational order) then AB, BC, CD and DA are pairs of supplementary angles.
