A matrix that has the same number of rows as columns is called a:a.Square matrixb.Diagonal matrixc.Identity matrixd.Row matrix

Break Down the Problem

1. Identify the type of matrix being described.
2. Compare each option with the description given.

Relevant Concepts

• A square matrix is defined as a matrix that has the same number of rows and columns.
• A diagonal matrix has non-zero elements only on its main diagonal and can be square but is not defined solely by the number of rows and columns.
• An identity matrix is a special type of diagonal matrix where all diagonal elements are 1.
• A row matrix is a matrix with only one row.

Analysis and Detail

• The description given matches the definition of a square matrix.
• The other options do not meet the criterion of having the same number of rows as columns.

Verify and Summarize

The analysis confirms that a matrix must simply have equal numbers of rows and columns to be classified as a square matrix.

Final Answer

The correct answer is: a. Square matrix.
