Question

Part B

Draw
parallel to
. You can draw
any length and place it anywhere on the coordinate plane, but not on top of
.

Find and record the ratio, n, of the length of
to the length of
. Then, multiply the lengths of
and
by n and record the resulting lengths.

Answer 1

In a diagram,

Then,

`(DE)/(BC)=n`

For example, suppose that n=2; thus,

`DE=2BC\longrightarrow2* CA`

We can form a new triangle DEF whose side EF is parallel to CA; therefore,

`\longrightarrow EF=2CA`
