Question

3. Classify the polygon below by its sides,convex/concave, and regular/irregular​

Answer 1

Answer:

The polygon is a concave polygon

The polygon is irregular polygon

Step-by-step explanation:

Convex polygon is polygon that has all interior angles less than 180°

In a convex polygon, every diagonal of the figure passes only through interior points of the polygon

A line drawn through a convex polygon will intersect the polygon in exactly two points

Some of convex polygons can be regular polygons

Concave polygon is a polygon that has one or more interior angles greater than 180°

In a concave polygon, at least one diagonal of the figure contains points that are exterior to the polygon

A line drawn through a concave polygon, can intersect the polygon in more than two points

Concave polygon never be a regular polygon

From the attached figure

∵ The polygon has one diagonal lies out the interior of the polygon

∴ The polygon is a concave polygon

∵ All the concave polygons are regular polygons

∴ The polygon is irregular polygon
