    Which of the following is true?

    A) PQR forms a scalene triangle

    B) PQR forms an isosceles triangle

    C) PQR forms an equilateral triangle

    D) None of the above

    Correct Answer: B

    Solution :

    As, \[PQ=QR=4\]units
    and \[PR=4\sqrt{2}\] units
    i.e., \[PQ=QR\ne PR\]
    Hence, \[\Delta PQR\]is an isosceles triangle.
