A convex angle is any angle of 180 degrees or less. So all angles less than 90 degrees
are certainly convex angles, but so are the angles between 90 and 180 degrees.

The measure of each of the interior angles of a convex polygon must be less than blank degrees?
180
Is a square a convex polygon?
Yes it is. It is surely a polygon and convex means all interior angles are less than a straight angle ( i.e.180 degrees).
Is a triangle convex or concave?
Three vertices polygons (aka triangle) can not be concave or convex because it doesn't have enough verticies to susustain an internal angle is less than or equal to 180 degrees. * * * * * Actually, a triangle IS a convex polygon. Convexity requires angle to be less than 180 degrees and since the three angles of a triangle sum to 180 degrees, each one of them MUST be less than 180 degrees!
Is a hexagon a convex figure?
It depends on what the angles are. If any of the angles have measurements greater than 180 degrees, it is concave. If all angles are less than 180 degrees, then it is concave. For example, a regular hexagon has six 120 degree angles, so it is convex. If there was a hexagon with five 90 degree angles and one 270 degree angle, it would be concave.
Is a concave quadrilateral less than 180 degrees?
The sum of the interior angles of a quadrilateral is 360 degrees (not 180). The sum of the exterior angles is also 360 degrees. Whether the quadrilateral is convex or concave is not relevant.
What is the definition of convex hexagon?
A convex hexagon is a six-sided polygon in which all interior angles are less than 180 degrees.

What is interior angles?
The angles between adjacent sides of a polygon that are interior to the polygon. If the polygon is convex, the interior angles are always less than 180 degrees. If it is concave, at least one interior angle will be greater than 180 degrees.

What are the types of polygons according to their interior angles?
Convex : all angles less than 180 degrees. Concave: at least one reflex angle (greater than 180 deg).
Is a star a convex polygon?
No. In a convex polygon, all the internal angles are smaller than 180 degrees.
What are 2 ways to classify a hexagon?
Convex(all interior angles are less than, or equal to, 180 degrees) and concave(one interior angle is more than 180 degrees).
What does a convex quadrilateral look like?
It is a plane area enclosed by four sides, such that each interior angles is less than 180 degrees.
How can you tell whether a quadrilateral is convex or not convex?
If any of the angles is greater than 180 degrees, the quadrilateral is concave.
