by crossing two number lines perpendicularl
A diamond has two pairs of parallel lines.
If the two lines are parallel, then you get 4 pairs of vertical angles. If the two lines are not parallel, then we get 6 pairs of vertical angles.
no
There are 56 pairs of congruent angles.

Here are three shapes that have two pairs of parallel lines: square parallelogram rectangle There are many polygons with at least two pairs of parallel lines. hexagon (has 3 pairs of parallel lines) octagon (has 4 pairs) decagon (has 5 pairs)
A diamond has two pairs of parallel lines.
Two intersecting lines form two pairs of equal and opposite angles.
A parallelogram has two pairs of opposite congruent lines
If the two lines are parallel, then you get 4 pairs of vertical angles. If the two lines are not parallel, then we get 6 pairs of vertical angles.
yes, intersecting lines form two pairs of congruent angles
Two pairs of adjacent angles are formed when two lines intersect each other.
They are intersecting lines.
no
2 pairs of two lines.
