Sia ? 5 years, 7 months ago

Let the given point be P and line be l
We draw two line segments PN & PM
such that
PM $\perp$ MN
We have to prove: PM > PN
In $\Delta \mathrm{P} \mathrm{NM}$
$\angle \mathrm{P}+\angle \mathrm{N}+\angle \mathrm{M}=180^{\circ}$ (Angle sum property of triangle)
$\angle \mathrm{P}+90^{\circ}+\angle \mathrm{M}=180^{\circ}$ (As PN $\perp$ MN, $\angle N=90^{\circ}$
$\angle \mathrm{P}+\angle \mathrm{M}=180^{\circ}-90^{\circ}$
$\angle \mathrm{P}+\angle \mathrm{M}=90^{\circ}$

Since angle can't be 0 or negative
Hence,
$\angle \mathrm{M}<90^{\circ}$
$\angle \mathrm{M}<\angle \mathrm{N}$
PN < PM (Side opposite to the greater angle is longer)
$\therefore$ Perpendicular line segment is the shortest.
Hence proved.
