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 a convex polygon?
yes
Is a triangle always convex?
yes they are
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 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.
