The cross section of a square pyramid taken perpendicular to the base that passes through the top vertex produces which two-dimensional shape?

triangle.  

Step-by-step explanation:

given: a square pyramid

to find : shape of cross section made when a plane perpendicular

             to base and passes through top vertex.                                                                  

when a plane cuts the square pyramid perpendicular to base and passes through top vertex we get a cross section made by its two equal slant height and side of the square.

therefore, we get a triangle or more specifically isosceles triangle.

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
