Question

Which of the following sets of lengths could be the sides of a right triangle? 10, 25, 35 22, 25, 36 18, 19, 25 20, 21, 29

Answer 1

Your set of lengths is 20, 21, 29
because all right triangles follow pythagorean rule (a^2+b^2=c^2)
20*20=400 and 21*21=441
400+441=841 and since 841=29*29
that means this is your answer set: 20, 21, 29
