The coordinate grid is an example of which undefined term? a. point b. line c. plane d. rectangle

C.plane

Step-by-step explanation:

We know that there are three undefined terms in geometry :-

1) point 2) line 3) plane.

Here point has no dimension, line has one dimension and a plane has two dimensions.

The coordinate grid has two dimensions ( length and width), then the  coordinate grid is an example of "plane".

Hence, C is the right answer.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
