# Math Help - Convex

1. ## Convex

Show that angles are not convex.

Not sure how to show this... Thanks!!

2. Is there supposed to be a picture?

3. No pictures. Just show that angles are not convex...

4. The question is utter rubbish. It's not angles that can be convex or concave, it's shapes or functions...

5. This question is taken directly from my book... I guess I'm supposed to use the definition of convex: A set S of points is called convex if the following condition holds: if A,B e S then AB is a subset of S.

Post the full question and its context (posibly with definitions of angle and convex). As it is this question is incomprehensible.

So S is the set of angles? What might those be, and how are we to costrue the composition of angles?

Also; what is the book?
