You can measure a triangle's length and width, but there is no depth. So that means a triangle has two dimensions.
Its called coordinates. These mark the position of a point in space. If you have 2-dimensional place, a pair of numbers can locate any point in that space. If you have 3-dimensional space, then ofcourse you need 3 coordinates (x,y,z) to locate a point in that space and so on for higher dimensions.
It means the coordinate (0, 0) - or in three dimensions, (0, 0, 0). That is, the origin, or starting point, of the coordinate system.
This question cannot be answered sensibly. A square metre is a measure of area, with dimensions [L2]. A metre is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
This question cannot be answered in a sensible way. A square metre is a measure of area, with dimensions [L2]. A centimetre is a measure of length, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information.
0. A point has 0 dimensions, no length, width nor height.
A point by definition has no dimensions
A point.
A location in space but no dimensions.
It has no linear dimensions.
It is a point.
Yes
A decimal point is a point, and that an ideal point has no dimensions (no width, no length, no height). So the answers is: there are no square feet in one decimal.
A point occupies zero dimensions.
That would be the point.
It is a point.
Theoretically there are many more. We can visualise 2 and 3 dimensions quite easily. One dimension is simply point. Higher dimensions can be described mathematically but are difficult if not impossible to visualise.
