hii dear !!
here ur answer!!
▪When two lines intersect at a point then the angle between them can be expressed in terms of their slopes and is given by the following formula:
tan θ = |
m
2−m11+m1
m2
| , where
m1
a
n
d
m2
are the slopes of the line AB and CD respectively.
If
m2−m11+m1.m2
is positive then the angle between the lines is acute. If
m2−m11+m1m2
><is negative then the angle between the lines is obtuse.
