Java program to calculate the area of a triangle using determinants
Aug 31, 2023 am 10:17 AM

This program is useful for anyone learning or working with geometry, as it demonstrates how to use basic arithmetic and algebraic calculations in Java, as well as how to use the Scanner class to read user input. The program prompts the user for the coordinates of three points of the triangle, which are then read in and used to calculate the determinant of the coordinate matrix. Use the absolute value of the determinant to ensure the area is always positive, then use a formula to calculate the area of the triangle and display it to the user. The program can be easily modified to accept input in different formats or to perform additional calculations, making it a versatile tool for geometric calculations. ranks of determinants
