Solution:−

Finding the distance between the points,

(PQ)² = (-5-4)² + (-1-3)²

= (-9)² + (-4)²

= 81 + 16

= 97

PQ = \sqrt{97}

97

Now,

(QT)² = (2+5)² + (-2+1)²

= (7)² + (-1)²

= 49 + 1

= 50

QT = \sqrt{50}

50

And,

(PT)² = (2-4)² + (-2-3)²

= (-2)² + (-5)²

= 4 + 25

= 29

PT = \sqrt{29}

29

So,

We can conclude that all side are different

PQ ≠ QT ≠ PT

Hence,

It is a Scalene triangle

Option c) Scalene triangle is correct
