Name four 4 sided figures

Answer 1

The base word for a many sided figure is polygon.

All four sided polygons are called quadrilateral

The sub groups of planar (2 dimensional) quadrilaterals are:-

• rectangle (a special kind of parallelogram)
• square (a special kind of rectangle (rhomboid))
• trapezium
• rhombus (an equilateral quadrangle which must also be a parallelogram)
• parallelogram

These are also called quadrangles (as they have four angles as well as four sides).

A three dimensional shape with four faces (surfaces) is called a tetragon

Tetragons have six edges and four vertexes, each where three edges and three faces meet. A triangular pyramid is a tetragon. it is the simplest three dimensional shape.
