The pythagorean triples are well known,
but it is not the only noticeable triangles with integer sides.
For instance triangle with sides 4,5,6 has angle A double of angle B
Find all integral sides triangles with the same property A=2B and sides less than 20.
n times angles
This can be generalized to angle A = n× B
Find the integer triangle with smallest sides and angle A = 5×B
Find all triangles with integer sides less than 20 and a 60░ angle.
of course, (1,1,1), (2,2,2) ... (20,20,20) are solutions, but any unequal sides triangle ?
