Question3. DEF\triangle D E F has vertices at D(8,2),E(1,3)D(8,-2), E(1,-3), and F(9,9)F(9,-9). Use special segments to determine if EFE F is the base of an isosceles triangle. ρ(8,2)\rho(8,-2)

Studdy Solution
Compare the lengths of the sides:
- EF=10EF = 10 - DE=52DE = 5\sqrt{2} - DF=52DF = 5\sqrt{2}
Since DE=DFDE = DF, DEF\triangle DEF is isosceles with EFEF as the base.
The segment EFEF is the base of an isosceles triangle.
