A nonconvex polygon is a concave polygon. All polygons with 4 or more sides can be concave. An arrowhead is an example of a concave quadrilateral. The back of an envelop (where the sides are folded and glued together) is a concave pentagon.
A concave hexagon or a concave octagon.
If the sign of the term involving x2 is positive then it is concave upward, provided everybody agrees what concave upwards means. Just like y=x2 is concave upwards.
No a parallelogram cant be concave because the only parrallelograms there are arent concaveParallelograms...*rectangle *square* rhombus*rhomboidMeaning of concave-polygons that have parts that go into the shape.
a concave polygon is that polygon whose at leat one of the angles is greater than 180 degree
lack of calcium in your body causes white stripes on teeth and nails.

A concave lens causes light rays passing through it to diverge because it is thinner at the center than at the edges. This shape causes the light rays to refract away from the optic axis, resulting in divergence.
Ask your Sociology teacher.....
A concave lens has a curved surface that curves inward on both sides, causing light rays to diverge after passing through. In contrast, a plano-concave lens has one flat side and one curved concave side, which also causes light to diverge but with less optical power compared to a fully concave lens.

A convex lens causes light rays to converge (come together) after passing through it, while a concave lens causes light rays to diverge (spread apart) after passing through it.
A concave lens has a thinner middle than the edges. This causes light rays passing through the lens to diverge, which is why concave lenses are often used to correct vision problems like nearsightedness.
Rusty baseboard nails are caused by moisture. The moisture can be caused by heavy rain and humidity or structural damage.
Yes, concave lenses are thinner in the middle and thicker at the edges. This shape causes light rays passing through them to diverge, making them useful for correcting nearsightedness.
A concave lens is also known as a diverging lens because it causes incident light rays to diverge away from a common point known as the focal point.
