No plane figure has four vertices unless it has four sides.
it is a plane and closed figure it has 4 corners and sides all the sides are equal
I AM A SPACE FIGURE WITH 5 FACES, 8 EDGES, AND 4 CORNERS. which SPACE FIGURE AM i?
The figure that has 4 sides and 3 corners is a triangle-shaped figure that has one of its corners truncated or cut off. This figure is called a "truncated triangle" or a "triangle with a missing corner" and has a unique shape that can be used in geometric and mathematical applications.
All plane figures except circles have corners, and even that is debatable that circles have an infinite number of corners. Corners are simply where the line tracing the perimeter of the shape changes direction. Without any corners, you would have not have a convex figure. You would have a line. ■
A single plane diamond (meaning not 3D or an object you hold in your hand) you draw on paper has 4 sides and 4 corners. ~
