Inverse of matrix is a matrix derived from another matrix such that if you multiply the two you get a unit matrix. Square matrices with a an inverse are called non singular matrices while those without an inverse are called singular matrices (determinant is zero). Inverses and determinant are only calculated for square matrices. Therefore, the determinant of a singular matrix is zero and also if A and B are inverses matrices then A and B must be square matrices.

Answer: LAST OPTION.

Step-by-step explanation:

The Pythagorean Theorem states the following relationship between the three sides of a triangle that has an angle of 90 degrees, known as "Right triangle":

$a^2=b^2+c^2$

Where "a"is the hypotenuse and "b" and "c" are the legs of the right triangle.

If the triangle ABC is a right triangle then AB must be equal to $BC^2+AC^2$ , then, you need to substitute the values into $a^2=b^2+c^2$ to check this:
