Step-by-step explanation:
\boxed{\rm{\orange{Given \longrightarrow }}}
Given⟶
⇢Points are P(4,3), Q(-5-1), T(2,-2)
\boxed{\rm{\red{To\:Find\longrightarrow }}}
ToFind⟶
⇢whether the given points form a triangle
\boxed{\rm{\pink{solution \longrightarrow }}}

⇢First we find the lengths PQ,QT,PTPQ,QT,PT
PQ=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}PQ=
(x

PQ=\sqrt{(4+5)^2+(3+1)^2}PQ=
(4+5)

PQ=\sqrt{9^2+4^2}PQ=

PQ=\sqrt{81+16}PQ=

\bf\,PQ=\sqrt{97}PQ=
97
QT=\sqrt{(-5-2)^2+(-1+2)^2}QT=
(−5−2)

QT=\sqrt{(-7)^2+1^2}QT=
(−7)

QT=\sqrt{49+1}QT=
49+1
\bf\,QT=\sqrt{50}QT=
50
PT=\sqrt{(4-2)^2+(3+2)^2}PT=
(4−2)

+(3+2)

PT=\sqrt{2^2+5^2}PT=

PT=\sqrt{4+25}PT=
4+25
\bf\,PT=\sqrt{29}PT=
29
\implies\bf\,PQ{\neq}QT{\neq}PT⟹PQ
=QT
=PT
∴The given points P,Q and T form a scalene triangle
