Question

Check whether (5,-2)(6,-4)&(7,-2) are the vertices of an
isosceless triangle.​

Answer 1

Answer:

a= (5,-2)

b=(6,-4)

c=(7,-2)

ab=√(5-6)^2 +(-2+4)^2

=√(1)^2 +(2)^2

=√1+4

=√5

bc = √(7-6)^2 +(-2+4)^2

=√(1)^2 +(2)^2

= √1+4

= √5

ca =√(7-5)^2 +(-2+2)^2

=√(2)^2 +(0)^2

=√4+0

=√4

=√2×2

= 2

isosceles triangle has two equal sides and one unequal side
