What else can I help you with?
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.

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.
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.
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
Which quadrilateral can have three acute angles?
A quadrilateral can have three acute angles if it is an irregular shape, specifically a type of concave quadrilateral. In such a case, the fourth angle can be obtuse or even reflex, allowing the sum of the angles to equal 360 degrees while still accommodating three acute angles. However, it's important to note that a convex quadrilateral cannot have three acute angles, as the fourth angle would then have to be obtuse to satisfy the angle sum property.
