Vertices (singular vertex) are the corners.
3 All triangles have 3 corners which are their vertices and it is the plural of vertex.
An octagon has has 8 corners.

A very common shape: the triangle. It is a flat plane that has only 1 face and always has 3 vertices or corners.
A sphere has no faces an corners. The term "faces" and "corners" are applied to polyhedrons, figures with flat surfaces.

A triangle is the only polygon with 3 corners (vertices). There is no polyhedron with 3 corners.
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. ■
Each square has four corners, and each triangle has three corners. 5 squares X 4 corners/square = 20 corners 3 triangles X 3 corners/triangle = 9 corners 20 + 9 = 29 corners total.
3 corners
An octagon has has 8 corners.
A sphere has no corners, it is a 3-D circle.
there are no corners and there are 3 faces
