No, intersecting lines form four pairs of supplementary angles
Perpendicular lines
They form four right angles.
Intersecting lines
Yes. They do. I disagree with the answer above, no they do not > that is 2 intersecting lines and there are only 2 angles there so the person above it incorrect
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.
Four pairs.
Four.
It must have lines which meet at the four vertices, but they cannot cross.
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).
360
Yes, by intersecting them.
