Does a quadrilateral have a convex or a concave angle?
concave
Calculation of contact angle?
Angle of contact is the angle between a tangent to the liquid surface at the interface and the solid surface inside the liquid. For concave surfaces, it is acute . For convex surface , it is obtuse.
What is the difference between a concave polygon and a convex polygon?
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
What is a definition for non convex polygon?
A simple polygon that is not convex is called concave, non-convex or reentrant. A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
How are convex polygons different from concave polygons?
A concave polygon has at least one interior angle greater than 180 degrees. A convex polygon has none of those.

What is the opposite of Convex?
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
Do a convex and concave mirrors obey the law or reflection Explain?
Yes, both convex and concave mirrors obey the law of reflection. The law of reflection states that the angle of incidence is equal to the angle of reflection. This means that light rays that strike a convex or concave mirror will follow this law and reflect off the mirror surface accordingly.
Is a hen decagon concave or convex?
It can be convex or concave.
What are three similarities between concave and convex mirrors?
Both concave and convex mirrors can create virtual images, which are images that cannot be projected onto a screen. Both types of mirrors follow the laws of reflection, with the angle of incidence being equal to the angle of reflection. Both concave and convex mirrors can be used in optical devices such as makeup mirrors or security mirrors.
What are two type of lenses?
convex and concave
What are the types of lenses and mirrors?
Lenses: converging (convex) and diverging (concave) Mirrors: concave and convex
Is concave curved in or out?
concave=in convex=out
