Question

Will angle sum property of quadrilateral hold if the quadrilateral is concave polygon? how?​

Answer 1

Step-by-step explanation:

Hence the required sum of all the angles of a concave quadrilateral is 360∘. Note: As with any simple polygon, the sum of the interior angles of a concave polynomial is 180∘×(n−2) where ′n′is the number of sides.

Answer 2

Answer:

I hope it helps :)

Step-by-step explanation:

Thus, it is a concave quadrilateral we have to find the sum of its all the interior angles. By angle sum property of a triangle, the sum of all the angles of a triangle is always 180∘. Hence the required sum of all the angles of a concave quadrilateral is 360∘.
