Let P be an intersection point of LM and HK.

Consider D KPM,

\ m Ð KPM + k + m = 180 ......(1) [Sum of the measures of angles of a triangle]

Similarly, D LPH,

m Ð LPH + h + l = 180^{ }......(2) [Sum of the measures of angles of a triangle]^{ }

From (1) and (2),

m Ð KPM + k + m =^{ }m Ð LPH + h + l

But Ð KPM @ Ð LPH [Vertically opposite angles]

\ m Ð KPM = m Ð LPH

Using the cancellation property of equality, we get

k + m = h +* *l
