Use the Pythagorean theorem a^2 +b^2 = c^2. In this case, 'a' would be FE and 'b' would be 6. Therefore, 8^2 + 6^2 =c^2
64 + 36 =c^2
100 = c^2
10 = c (which would correspond to DF)

this is best solved using the Pathergerious theorum (I probably spelled his mane wrong) where on all right triangles the sum of the two smaller sides squared will equal the the largest side squared or in this case (8 x 8) + (6 x 6) is going to equal df squared, in this case answer would be the square root of 100, or 10
