Given three positive numbers a, b, c, where c is the largest number, return true if the triangle with sides a, b and c is right-angled. Otherwise, return false.
This is a good problem to refresh basic geometry
The checking should include a random Pythagorean triple (given random natural numbers a>b: a^2-b^2, 2ab, and a^2+b^2 form a Pythagorean triple). For the checking right now, a~=2 passes the tests.
Basic triangle math plus if statements. Great example
This reminds me the old good days ... basic geometry as Sreeram Mohan said :)
What is wrong with this code?
if c==sqrt(a^2 + b^2)
Should add tolerance of 10*eps to make this function practical. Otherwise you can have a triangle with a 89.9999999 deg angle and it will say it is not a right triangle. Matlab is a numerical language.
This user (mohamed elbesealy) appears to have gamed the system, with fraudulent "likes" of this unremarkable solution submitted by 'sock-puppet' accounts. —DIV
mmm c is always grater than a and b
