Answer 1

Answer:

Verify experimentally, if to lines intersect each other, then. the vertically opposite angles are equal. the sum of two adjacent angles is 180o 

Answer 2

Answer:

If two lines intersect eachother at a point ,then

1)Vertically opposite angles are equal.

2)adjacent angles are supplementary.

3)sum of all angles around a point is 360°
