A polygon that lies entirely on one side of any line containing its side. 🔹 2. Key Formulas for Convex Polygons For a polygon with n sides: Sum of interior angles: Sum of exterior angles: Always 360∘360 raised to the composed with power (one at each vertex). Number of diagonals:

In grades 10-11, polygons are often viewed as faces of polyhedra: Bases are equal polygons in parallel planes. Pyramids: Base is a polygon; lateral faces are triangles. geometriia 10-11 klass otvety na voprosy mnogougolniki
