Explanation: Regular hexagons are comprised of six equilateral triangles; in our question, these triangles each have side length 4 (see diagram). The length of a diagonal is equal to two times the length of the side. In this instance, the answer is 8.

In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°. It is also a regular polygon, so it is also referred to as a regular triangle.

When two of the faces meet, they form a line segment called an edge. When three edges meet, they form a point, which is called a vertex (the plural of vertex is vertices). A triangular prism has 5 faces, 9 edges, and 6 vertices.

Maths keeps one mentally active. In an octagon, by joining one vertex to the remaining vertices you will get 6 triangles. This can also be figured out as follows: the sum of the interior angles of an octagon is (2n-4)*right angles or (n-2)*triangles.

Thus, total number of ways = 60 + 36 + 20 = 116. Method 2 : First, select any three points to make a triangle.

A rectangular prism has 6 faces, 8 vertices, and 12 edges. A cube, just like a rectangular prism, has 6 faces (all squares), 8 vertices, and 12 edges. A triangular prism has five faces.
