No, intersecting lines form four pairs of supplementary angles
yes, intersecting lines form two pairs of congruent angles
2 pairs
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.
4 angles
They are intersecting lines.
Yes, a pair of intersecting lines always forms a pair of vertical angles.
yes
Yes.
All of them. If its truly intersecting lines, they have to form right angles. All of them. If its truly intersecting lines, they have to form right angles.
They would be called intersecting lines.Intersecting lines form Vertically Opposite Angles. Each pair of opposite angles (sharing only a vertex) is congruent. Each of the four pairs of adjacent (sharing a side) angles forms a straight angle (they add to 180o).
intersecting lines * * * * * Non-perpendicular intersecting lines. Or else the angles would be right angles.
