    Answer:

    (4,3), (−4,8), (−4,3)

    (2.5,−4), (0,0), (0,−4)

    Step-by-step explanation:

    On plotting on graph all form right angled triangle.

    Dimension of all triangles and tanФ

    1. Base=2 Height=5   tanФ  2.5
    2. Base=5 Height=3   tanФ  1.6
    3. Base=8 Height=5   tanФ  1.6
    4. Base =2.5 Height=4   tanФ  1.6

    [Here base and height can be interchanged if needed]

    Ratio of perpendicular and base of last two triangle is equal.

    First two are not congruent to any of other triangle but 3rd and 4th triangle are congruent .

    Their coordinates are:

    (4,3), (−4,8), (−4,3)

    (2.5,−4), (0,0), (0,−4)
