This is less than 180, as is this, but this angle is also greater than 180 degrees. And so, the answer must be (C). (C) is a concave polygon. But let’s check option (D) and (E). We might recall that in a concave polygon, one or more of its diagonals will lie outside of the shape itself.
Here are a few examples of convex polygons. Concave Polygons – A concave polygon is a polygon with at least one interior angle greater than 180°. In concave polygons, not all diagonals are in the interior of the polygon. Here are a few examples of concave polygons. Difference between Convex and Concave Polygon. 3. Simple and Complex Polygon:
Concave. Curved inwards. The green shape is concave but is not a polygon. A polygon (which has straight sides) is concave when there are “dents” or indentations in it (where at least one internal angle is greater than 180 degrees). The vertices are inwards as well as outwards.
Jul 18, 2012 · Concave: A concave polygon has at least one interior angle greater than 180 degrees. A common way to identify a concave polygon is to look for a "caved-in" side of the polygon. Convex: A convex polygon contains no interior angles greater than 180 degrees. Diagonal: A diagonal is a line segment in a polygon that connects nonconsecutive vertices
Sep 9, 2023 · Concave and Convex Polygons Concave Polygons. Examples: Star-shaped figures, snowflakes, some irregular polygons. Properties: Have at least one interior angle greater than 180°. Have vertices that “cave” inward. Ways to Remember: “Concave” has a “cave” or an inward dip; you can imagine it as a polygon that’s been “pinched ...
A concave polygon is a polygon that has at least one interior angle greater than 180 degrees. A four-sided concave polygon is also known as a quadrilateral. Some examples of concave polygons include:-Trapezoids-Parallelograms-Rhombuses . What are the properties of a concave polygon? The properties of a concave polygon depend on the number of ...
Here are some characteristics of concave polygons: 1. It has at least one interior angle greater than 180 degrees. This angle is also known as an obtuse angle. 2. The opposite of a concave polygon is a convex polygon, which has all interior angles less than 180 degrees. 3. A concave polygon can have any number of sides, starting from three or ...
