" "
A(5,4), B(7,9) and C(5,8)

Bisectors:

D(6,8.5) and G(7.25,6) with DG=2.8 " units"
E(6,6.5) and G(7.25,6) with EG=1.35 " units"
F(5,6) and G(7.25,6) with FG=2.25 " units"

Explanation:

Triangle ABC:

Vertices: A(5,4), B(7,9) and C(5,8)

Construct a perpendicular bisector:

  1. for side AB,

    find the mid-point: E(6,6.5)
    " "
    2. for side BC,

    find the mid-point: D(6,8.5)
    " "
    3. for side AC,

    find the mid-point: F(5,6)

Measure the magnitudes of the perpendicular bisectors:

EG=1.35" Units"

FG=2.25" Units"

DG=2.8" units"
