What exactly does that mean?

Is there a much easier way of saying the same thing?

**NOT DRAWN TO SCALE**referring to math questions.

What exactly does that mean?

Is there a much easier way of saying the same thing?

Suppose they gave us $\displaystyle \Delta ABC$ with: .$\displaystyle AB = 10,\;BC = 12,\;AC = 5$

And suppose they supplied this diagram:Code:`A`

10 * * 5

B * * * * * * * C

12

It is only a rough sketch . . . It is**not**"drawn to scale."

$\displaystyle AB = 10$ doeslook like it is twice $\displaystyle AC = 5$, does it?*not*

It gives an*idea*of what the triangle looks like.

. . $\displaystyle AC$ is the shortest side and $\displaystyle BC$ is the longest side.

But I wouldn't guess the size of the angles from that diagram.

. . It looks like $\displaystyle \angle A$ is acute, but actually it's about 101°.
