Does a quadrilateral have a convex or a concave angle?
concave
Is an acute angle a concave or convex angle?
All angles < 180 degrees are concave. An acute angle is < 90 degrees. So, all acute angles are concave.

What is concave hexagon?

Which polygons are concave?

What is a concave m polygon?

What effects does light have on concave and convex mirrors?
Light has little or no effect on a mirror. The mirrors follow the rule: "the angle of incidence equals the angle of reflection". Concave mirrors concentrate light to a point and convex spread it out.
What is the largest angle in quadrilateral?
Any angle <360 degrees is possible, though it would be a concave quadrilateral if the angle were greater than 180 deg.
How can you determine if a polygon is concave?
It must have at least one internal angle which is a reflex angle - that is, between 180 and 360 degrees.
