    Hint: You must use the following theorems. 1) Distance formula for finding the lengths of all the sides. 2) Pythagorean theorem for confirming that we have a right triangle. 3) Heron's formula for finding area.

    not symmetric w.r.t y axis (-2,0) is correct

    if u flip the upper half and lower half, u get the same graph, here x-axis remains axis of symmetry
