Determine whether ∆PQR is a right triangle.
Using distance determine if the triangle is an isosceles triangle.

d(PQ) =sqrt((5-0)^2+(0-5)^2) = 5sqrt(2)
d(QR) =sqrt((5-10)^2+(0-5)^2) = 5SQRT(2)
d(PR)=sqrt((0-10)^2+(5-5)^2) =10
Check
(5sqrt(2))^2+(5sqrt(2))^2=100
sqrt(100)=10 PR is hypotenuse hence right triangle
Two sides are equal so its isoscles triangle
