Question

which term considered undefined a. cube b. circle c. point d. triangle​

Answer 1

Point is considered as undefined.

• According to the geometry, a point has no dimensions and it's basically a location. We represent the point as a dot which have geometrical dimensions but in reality, an ideal point has no dimensions.
• This absence of geometrical dimensions, makes a point, undefined.
• Rest of the geometrical shapes are defined because they can have proper geometrical dimensions. And these defined shapes are made out of undefined terms like point, line and plane.
