Procedure :
- What are intersecting lines?
- Identify two lines cross each other in a plane i.e. lines 'g' and 'f' intersect at point 'A'
- Identify intersecting lines (two or more) meet only at one point always and also can cross each other at common vertex (which is the point of intersection).
- Identify the angles formed at common vertex 'A'
- Identify two pairs of opposite angles
Evaluation at the end of the activity
