Is the union of two nonconvex sets nonconvex?
Not necessarily.
How are a parallelogram and triangle related?
They are both convex polygons.
Is it possble for a triangle to have a right angle and an obtuse angle?
Not a plane triangle. With a triangle on a convex surface (eg on the surface of a sphere), the answer is Yes.
Is a triangle a convex shape?
Yes, it is! I had this question last night on an assignment for school, and "googled" it because I didn't really know, but yes, it is convex.
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 triangle a convex?
yes a triangle is a convex
Is the union of two nonconvex sets nonconvex?
Not necessarily.
Is a triangle a convex polygon?
yes
Is a triangle always convex?
yes they are
What is an example of convex polygon?
A triangle.
What has the author Aleksandr Moiseevich Rubinov written?
Aleksandr Moiseevich Rubinov has written: 'Abstract convexity and global optimization' -- subject(s): Convex programming, Mathematical optimization 'Lagrange-type functions in constrained non-convex optimization' -- subject(s): Lagrangian functions, Nonconvex programming
Is a convex polygon always a regular polygon?
No, a scalene triangle, for example, is a convex poygon but it is not regular.
Is a triangle concave?
Yes, a triangle is always concave. * * * * * How wrong can you get! A triangle is always convex and NEVER concave.
How are a parallelogram and triangle related?
They are both convex polygons.
Is every triangle a convex?
Maybe Maybe
Is it possble for a triangle to have a right angle and an obtuse angle?
Not a plane triangle. With a triangle on a convex surface (eg on the surface of a sphere), the answer is Yes.
How can you find a generalization for a triangle a parallelogram and a convex shape?
A parallelogram cannot be generalised to a convex shape with an odd number of sides.
