To explain about trigonometry.

Trigonometry is the study of triangles. It is the branch of mathematics that deals with the relationship between angles and sides in triangle. There are six trigonometric function namely sine, cosine, tangent, secant, cosecant and cotangent functions. These trigonometric functions has been used to find the angles and sides of triangle.

In a right angled triangle, if

What is the inradius of the octahedron with sidelength a?

1) Determine the height of one of two constituent square pyramids by considering a right triangle, using the fact that the height of the equilateral triangle is

2) Now cut the (solid) octahedron along 4 of these latter heights, i.e. across two non-adjacent vertices and two midpoints of parallel sides of the ''square base''. (Figure 1)

Consider the resultant rhombic polygon, whose sidelength is

So the question becomes: Is there a still simpler proof?
