A nonstandard unit is a unit of measure expressed in terms of an object such as a shoe, toothpick, paper clip or stick of gum, according to the Catholic School Department Diocese of Sacramento. It can also be expressed in informal terms such as a hand span or body length.
Know MoreNonstandard units are typically used when initially introducing young learners to various attributes and concepts involving measurement. These concepts include more of and less than, measuring by laying objects end to end, sorting and classifying into categories according to size, comparing the lengths of two objects by using a third, describing objects in terms of relative size, and ordering objects by length.

Full Answer >You can calculate the perimeter of any object by adding the length of its sides. With a few simple measurements, you can quickly find the perimeter of a triangle.
Full Answer >A vertex is a corner on a polygon, polytope or polyhedron, and when faces, facets or edges of an object come together, a vertex forms; however, because a sphere features no meeting points, it has no vertices. Even though a sphere does have one continuous surface, its lack of meeting points with any other surface means that it technically has no faces. Spheres have no lines, so they also have no edges.
Full Answer >Technically, a pendulum can be created with an object of any weight or shape attached to the end of a rod or string. However, a spherical object is preferred because it can be most easily assumed that the center of mass is closest to the pivot's end, thereby limiting variables.
