Question

give any two differences between concave and convex quadrilateral

Answer 1

Answer:

In a convex quadrilateral each angle measures less than 180°. ... In a concave quadrilateral at least one angle is a reflex angle, i.e., an angle larger than 180°. In figure, ABCD is a concave quadrilateral because a line joining the vertices A and C is going outside the quadrilateral region.

Answer 2

Step-by-step explanation:

A convex quadrilateral has interior angles 180 degrees or less. A concave quadrilateral has an interior angle measure greater than 180 degrees. Most common quadrilaterals are convex, and they do not have any interior angle measure greater than 180 degrees
