How is a triangle and a circle similar?
A closed, convex, plane (2-dimensional) shape.
Differentiate convex and non convex polygon?
A convex polygon is one with no angle greater than 180 degrees. A non-convex polygon is one that is not without such an angle.
Is a pentagon convex?
A regular pentagon is convex. By taking a regular pentagon and shortening or lengthening one or more sides, an infinite number of possible convex pentagons can be created. A convex polygon is defined as a polygon such that all internal angles are less than or equal to 180 degrees, and a line segment drawn between any two vertices remains inside the polygon. It is possible to have non-convex (concave) pentagons; there are infinite number possible ways to do this, too.
In which triangle do the three altitudes intersect outside of the triangle?
Obtuse Triangle
If a median of a triangle is also an altitude of a triangle then is the triangle isosceles?
Yes
Is a triangle always convex?
yes they are
Is a triangle a convex polygon?
yes
What is an example of convex polygon?
A triangle.
Is triangle is a convex or nonconvex?
A triangle is normally nonconvex on a flat surface
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.
What is the sum of the measures of the exterior angles of any convex triangle?
A triangle must be convex, so that adjective is redundant. The sum of the exterior angles of any polygon, whether convex or concave, an no matter how many sides, is 2*pi radians. That is equal to 360 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!
