There are 5 triangles in an heptagon
4-sided pyramid.
Shapes that have fewer than 5 vertices include triangles (3 vertices), quadrilaterals such as squares and rectangles (4 vertices), and circles (0 vertices, as it is defined by its center point). These shapes are classified based on the number of corners or points that define their boundaries. Shapes with fewer vertices are typically simpler in structure and have fewer sides.
A square pyramid has 5 faces. The four side faces are triangles, and the base is in the form of a square. This pyramid has 5 vertices and 8 edges.
