A concave line is a line that caves in.
i think you have to put both of the points onto the line

Concave, because you can connect the corners from the outside.
A concave polygon is a type of polygon that has at least one interior angle greater than 180 degrees, which causes it to "cave in" toward the interior. This results in at least one vertex pointing inward, creating a shape that can have both convex and concave angles. Additionally, a line segment drawn between two points within a concave polygon may lie outside the polygon, distinguishing it from convex polygons where all such segments remain inside. Concave polygons can have any number of sides, but their defining characteristic is the presence of at least one concave angle.

If the opportunity cost is constant, the PPF is a straight line; when the opp. cost of a good rises when it is produced more, then concave.

Formally, a polgon is concave if there is at least one pair of points in (or on) the polyhedron such that the straight line joining the two points is not wholly inside (or on) the polyhedron.In less formal terms, a concave polygon is one which has a bit going inwards.

i dont think any1 knows * * * * * A concave polygon has at least one reflex angle. Equivalently, in a convex polygon, a line joining ANY two points in (or on) the polygon lie wholly within (or on) the polygon. In a concave polygon there are at least two points for which the line joining them does not lie wholly inside (or on) the polygon.

Concave mirrors can be purchased from a number of places, specialist mirror stores would be able to stock these. Also on-line sites such as Amazon also stock these mirrors.
