Eight.
Four and opposite angles are equal.
20....or maybe 18
3 intersecting lines, because none of the three points are right angles.
2 pairs
If you draw two lines intersecting, you'll see that they create 4 angles.

4 angles
We'll get a n number of vertical angles (pairs)

None but its diagonals are perpendicular lines intersecting each other at right angles.
there are 4 intersecting lines

Two pairs of adjacent angles are formed when two lines intersect each other.
