Answer 3

Not familiar with this but it looks relatively simple... and we could have used it on the last question too!

Answer 4

(– 4, 6, 10)
+6,-2,-4
(2, 4, 6)
+6,-2,-4
+6,-2,-4
(14, 0, –2)

Answer 5

You can also find the vectors between points, and use dot product to show the angle between them is zero... but that's not really using the sections formula.
