Which of the following is not a characteristic of a point?

The following which is not a characteristics of a point is:

                       Flat surface.

Point--

( The other undefined terms of geometry is:

          Line and a Plane)

         Hence, the answer is: Flat surface

Flat surface

Step-by-step explanation:

If you study geometry, one of the undefined terms you learn is a point.  The others are lines and planes.  However, a point is undefined, has no depth or width, and is in fact named with one capital letter.  What a point is not is a flat surface.

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
