They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
A pair of angels in a straight line formed by a line or half-line meeting it is called adjacent angels. Adjacent angels will add up to 180°.
More info needed. Are the 2 lines parallel, perpendicular, or? are the angles that you are interested in on opposite sides of the intersecting line or the same side. The intersecting line is called a transversal. If the original lines are parallel, angles between the 2 lines on opposite sides of the transversal are called alternate interior angles, etc.
A pair of supplementary angles.
vertical angles
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
Linear Pair
they are called supplementary angles. a straight line has 180 degrees each side and two adjacent angles forming 180 degrees are called supplementary angles.
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
The angles are called supplementary if they add to 180 degrees. Where the two angles are adjacent, they form a "linear pair" such that their farthest sides lie on the same line.

Actually, It is this. Question: Angle 1 and 4 are called ___ angles? Answer: Supplementary
Only the pair of angles opposite the line of symmetry are equal. The other two angles that are bisected by the line of symmetry are not equal. if these angles were equal then the shape would be a rhombus.
