Question

I am willing to do the work, I want to understand. I will post possible answer choices once the thread becomes open.
Which figure is convex?

Answer 1

A convex polygon is defined as a polygon with all its interior angles less than 180°. This means that all the vertices of the polygon will point outwards, away from the interior of the shape.
That being said, my answer selection is figure A. If I am incorrect, please explain. I'm here to learn!

Answer 2

There are 2 types of polygons:

convex polygons
concave polygons

Answer 3

if it is possible to plot 2 points in a polygon, and the line connecting these two points goes OUTSIDE the polygon, then this polygon is concave. If a polygon is concave, then it is not convex

Answer 4

here's an example of a concave polygon

Answer 5

here are 2 points IN the polygon

Answer 6

but the line connecting the two points goes OUTSIDE of the polygon
