  1. LM = √(5^2+3^2) = √34
    LN = √(4^2+1^2) = √17
    MN = √(1^1+4^2) = √17

    So, it is isosceles.
    But since

    √17^2 + √17^2 = √34^2
    17+17 = 34

    it is a right triangle.

  2. How do you know its a right angle when the answer is 34 i thought it has to be 90?

  3. I'm not talking about angles, but sides. Remember the Pythagorean Theorem?

    a^2 + b^2 = c^2
