  1. Step-by-step explanation:

    A(1,−3),B(2,−5),C(−4,7)

    AB=

    (1−2)

    2

    +(−3−(−5))

    2

    (−1)

    2

    +2

    =

    5

    BC=

    (2−(−4))

    2

    +(−5−7)

    2

    36+144

    180

    =6

    AC=

    (−1−(−4))

    2

    +(−3−7)

    2

    =

    25+100

    =

    125

    =5
