Question

Check whether the points (5 , -2 ) , (6, 4 ) and( 7 , -2 ) are the vertices of an isosceles triangle​

Answer 1

In an isosceles triangle , any 2 of the 3 sides are equal .

Let the three points be P (5,-2) , Q(6,4) & R(7,-2)

In order to be isosceles ,

Either

PQ=PR

or

PQ=QR

or

PR=QR

We calwlete the value of PQ,QR&PR by distance formula
