- d is distance, (x_1,y_1) and (x_0,y_0) two points on a coordinate grid.
In our case :

No they don't.
Phythagorean triple is when the sum of the squares of two numbers is equal to the square of another number.
20^2 + 24^2 = 400 + 576 = 976
31^2 = 961
20^2 + 24^2 should have been equal to 31^2 but that's not the case. So, the side's length don't form a triple.
Hope it helped!
