Question

Prove that the points P(3,5), Q(-2,0) and R(7,0) are the vertices of an Isosceles triangle.
Plz, help me ​

Answer 1

Answer:

PQ =√(-2-3)^2 + (0-5)^2 = √50

QR = √(7+2)^2 + 0= √81

RP = √ (3-7)^2 + (0-5)^2 = √41

None of two sides are same. All the sides are different. This cannot be an isosceles triangle.
