 07. Create a base class called Matrix. Use this class to store a matrix of 2 x 2 of  int type values that could be used to calculate determinants and create matrices. Create class CalculateDeterminant which will calculate the determinant of a matrix. Using these classes, calculate the determinant of the matrix.

Create a class compute which will determine whether a triangle is a right angled triangle. Using these classes, design a program that will accept dimensions of a triangle, and
 display the result. (Summary: Prove that triangle is a right angled triangle using pythagoras theorem).
