Question

If the length of AO is three times the length of CO, the length of DC is

three times the length of OC

three times the length of DO

one-third of the length of AC

one-third of the length of AB

Answer 1

tips?

Answer 2

one-third of the length of AB

Answer 3

is that right?

Answer 4

sorry i forgot all about this looking it up *.*!

Answer 5

one-third of the length of AB ?

Answer 6

It would be one-third of the length of AB by similar triangles. Note that \(\Delta DOC\)~\( \Delta AOB \), so the side lengths must be in proportion.

Answer 7

k

Answer 8

DC is similar to AB, and since CO is one third AO, it must be that DC is one third of AB.
