# What are intersecting lines?

# What are intersecting lines?

# Identify two lines cross each other in a plane

# Identify two lines cross each other in a plane i.e. lines 'g' and 'f' intersect at point 'A'

# Let lines P and Q intersect at point O

# 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 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).
