triangle
Most shapes have no right angles. Circle, pentagon, hexagon etc. Ones that do include the square and some triangles.
square
Shapes, angles, lines, points, and planes.
3 sided shapes are triangles
A dodecagon has 12 sides
Press the buttons in the edge and move the shapes into the same shapes.
The answer could depend on the way in which the shapes are connected but I doubt that it has any specific name.
Hard-Edge
You cannot have such a shape because either the shapes must meet at an edge or the vertices must be joined by an edge.
A place where two faces meet is called an edge.
An edge is the curve formed where two of the planes defining [bordering] the 3D shape meet. It is often a straight line where the planes defining the shape meet but, as in the case of a hemisphere, an edge could be a circular boundary where the flat face meets the curved face.
* Fist * Shuto - Knife edge * Chicken Beak * Crane Beak * Tiger Claw
Circles and discs (separate things as a circle is the edge or circumference only wereas a disk is inside of circle also)
Edges are sides in terms of 2D shapes but they are the place where two sides of a 3D shape meet ie. the sharp edge that runs between corners
A color edge is a manifestation of the element of contrast in composition. It occurs when two colors meet or interact within a composition, creating a clear boundary or separation that can emphasize shapes or forms within the artwork.
EDGE is a line. ... 2D --------------------------------- 2D: head ~ ellipse. 3D: head ~ elliptoid. Half head ~ hemieliptoid.
