2-dimensional shapes, with three straight sides have three vertices.
triangles
Triangles have 3 sides.
There two different shapes that have more than one vertex. One is a triangle it is a plane figure that has three straight sides and three angles and a quadrilateral which a four sided figure.
Yes * * * * * Not true! A circle is a 2-d shape that is not a polygon. A polygon must have sides that are straight lines. A 2-d shape need not have straight sides.
2-dimensional shapes, with three straight sides have three vertices.
Shapes with straight sides are called polygons
Polygons are shapes that have three or more sides * * * * * There is more to a polygon. It is a closed, plane (flat) shape. The three or more sides must be straight lines.
Oh, dude, we're talking about polygons here! Yeah, polygons are shapes with straight sides, like triangles, squares, pentagons, hexagons, and so on. So, if it's got straight sides and looks like it belongs in a geometry textbook, it's probably a polygon. Cool, right?
A quadrilateral.
A point. Other shapes may not have straight sides but that does not mean that they do not have sides.
No
Most shapes will have more than two sides. If the sides are straight lines, the shapes MUST have more than two sides.
There are no polygons (shapes with only straight-line sides) with fewer than three sides, but if you allow shapes with curved sides there are many possibilities. Examples include semicircles, annuli (donut shaped), and crescents.From Caromal, and Izzyk9God just say a CONE!!!
triangles
Common shapes with less than 4 sides are triangles and circles ( but the circle has no straight sides).
Triangles have 3 sides.
