WebJan 31, 2024 · 1. Define the formula. The formula to find the number of diagonals of a polygon is n (n-3)/2 where “n” equals the number of sides of the polygon. Using the distributive property this can be rewritten as (n 2 - 3n)/2. You may see it either way, both equations are identical. [9] WebBut when I try it this way, it does work (the folded part sits perfectly on top, all edges matching): So this is a Line of Symmetry. Triangles. A Triangle can have 3, or 1 or no lines of symmetry: Equilateral Triangle ... A Regular Hexagon (6 sides) has 6 Lines of Symmetry. A Regular Heptagon (7 sides) has 7 Lines of Symmetry. A Regular Octagon ...

WebA hexagonal prism is a prism that has hexagon-shaped bases that are parallel to each other. The hexagonal bases are joined by six rectangular side faces. Hexagonal prisms have a total of 8 faces, 12 vertices, and 18 edges. If the prism is regular, the sides of the hexagonal faces are equal and all the lateral faces are also equal.
