- A convex polygon has no angles pointing inwards. More precisely, no internal angle can be more than 180°. If any internal angle is greater than 180° then the polygon is concave. (Think: concave has a "cave" in it)

Aug 3, 2023 · A concave polygon, also known as a non-convex polygon, has at least one of its interior angles measuring more than 180°. Some diagonals of a concave polygon lie outside the closed figure. All concave polygons are irregular since all the interior angles are of different measures.
Sep 9, 2023 · Convex Polygons. Examples: Squares, rectangles, triangles, regular hexagons. Properties: All interior angles are less than 180°. No vertices “cave” inward. Ways to Remember: Convex polygons “bulge” outward, with no indents or “caves.”
Jan 23, 2009 · The polygon is convex if the z-components of the cross products are either all positive or all negative. Otherwise the polygon is nonconvex. If there are N points, make sure you calculate N cross products, e.g. be sure to use the triplets (p [N-2],p [N-1],p [0]) and (p [N-1],p [0],p [1]).
May 7, 2024 · All convex polygons fall into the regular polygon category. However, the convex label mainly focuses on the interior angles of a polygon. For an n-sided polygon to be considered convex, all the angles equal 180 degrees or less.

If any internal angle is greater than 180° then the polygon is concave. (Think: concave has a "cave" in it) Simple or Complex. A simple polygon has only one boundary, and it doesn't cross over itself. A complex polygon intersects itself! Many rules about polygons don't work when it is complex. More Examples. Irregular Hexagon. Concave Octagon.
A convex polygon is a closed figure where all its interior angles are less than 180° and the vertices are pointing outwards. The term convex is used to refer to a shape that has a curve or a protruding surface. In other words, all the lines across the outline are straight and they point outwards.
Nov 21, 2023 · If a polygon isn't convex, then it's classified as a concave polygon. What does a concave polygon look like? A concave polygon has at least one interior angle that measures more...
