"Vertices" is the plural form of "vertex." In mathematics, a vertex refers to a point where two or more lines or edges meet to form a corner or an angle. In the context of geometry, vertices are often associated with polygons and polyhedra.
For example, in a triangle, each of the three corners is a vertex. In a cube, each of the eight corners is also a vertex. These vertices help define the shape and structure of the geometric object.
To find the vertices of a geometric figure, you need to examine the specific object. For simple shapes like triangles or quadrilaterals, you can visually identify the corners as vertices. In more complex figures, such as irregular polygons or 3D shapes like polyhedra, you may need to count the corners or use specific formulas to determine the coordinates of the vertices.
