The icosahedral shape, which has 20 equilateral triangular faces, approximates a sphere, while the helical shape is cylindrical.

The shape of the Earth approximates an oblate spheroid, a sphere flattened along the axis from pole to pole such that there is a bulge around the equator.

Since a conductor is a flexible object with uniform weight per unit length, the geometric shape of a conductor strung on towers approximates that of a catenary.

A river delta is so named because its shape approximates the upper-case letter delta.

Its shape very roughly approximates a right triangle, with the hypotenuse corresponding to the peaks of the Sobaek mountains.

In this sense the broccoli's shape approximates a natural fractal; each bud is composed of a series of smaller buds, all arranged in yet another logarithmic spiral.

The Earth is not a sphere, but an irregular shape approximating a biaxial ellipsoid.
