How to Find a Triangle Within a Triangle Using Java Code

Instructions

1

Create a class that represents a triangle, storing three points representing x and y coordinates. These points will represent the basic triangle (Source 1):

class T

public static void main(String[] args)

int[] s1 = 10, 6;
int[] s2 = 16, 16;
int[] s3 = 4, 0;




2

Determine the midpoint of two different sides (Source 1):

int diff_side1x = s2[0] - s1[0];
int diff_side1y = s2[1] - s1[1];
int[] mid_side1 = diff_side1x + s1[0], diff_side1y + s1[1];

int diff_side2x = s2[0] - s3[0];
int diff_side2y = s2[1] - s3[1];
int[] mid_side2 = diff_side2x + s3[0], diff_side2y + s3[1];

3

Connect the two midpoints to one of the already existing points. These three points will form a triangle inscribed in the original (Source 1):

//original triangle
s1;
s2;
s3;

//internal triangle
s3;
mid_side1;
mid_side2;

//internal triangle
s2;
mid_side1;
mid_side2;
