Question

check whether (5 -2) (6 4) and (7 -2) are the vertices of an isosceles triangle

Answer 1

I hope this will help you

Answer 2

Answer:

Put:     A = ( 5, -2 )        B = ( 6, 4 )        C = ( 7, -2 )

Method 1   ---  Calculating lengths

AB = √( (6 - 5)² + (4 - -2)² ) = √( 1² + 6² ) = √37

BC = √( (6 - 7)² + (4 - -2)² ) = √( 1² + 6² ) = √37

As AB = BC, this points make an isoscles triangle
