The hypotenuse of a right angled triangle has its ends at the points `(1," "3)` and `(" "-4," "1)` . Find the equation of the legs (perpendicular sides) of the triangle.

Explanation

Let, in `DeltaABC`
`/_B=90^(@)`
`A-=(1,3)`
and `C-=(-4,1)`
Equation of a line `BC` passing through `C` and parallel to `x`-axis is,
`y=1`
Similarly equation of a line `AB` passing through `A` and parallel to `y`-axis is
`x=1`
