Hey , its a Triangle
A nonagon has 9 edges.
that is impossible!!! you cant have 2 edges make a shape
The geometric shape that would almost match those characteristics is a triangular pyramid, as it would have four faces rather than three
A non geometric shape can be defined as shapes with irregular contours, and whose edges are not straight. On the other hand, geometric shapes are shapes with regular contours and straight edges such as squares, triangles, or circles. ~by Kate Wellsonberg
The only regular geometric shape that fits your description would be an elipse. That is a circular shape so it has no straight edges, and appears to be a squashed circle.
pentagonal prism
It is a triangular prism
I believe it is a cone, a cylinder has three faces.
It is a cuboid which has 6 faces, 12 edges and 8 vertices
A net for a geometric solid is the 2-D pattern for constructing the 3-D shape.
It is a triangular based pyramid which also has 4 vertices.
The simplest answer is a cylinder (although you could squish it a bit to make something slightly different). It has a curved rectangular face, two circular faces, and two curved edges.
