5 Pythagoras developed a formula for finding Pythagorean triads (a, b, c). If one number in the triad is a, the formulas for the other 2 numbers are b= 1/2(a squared - 1)
and c = {(a +1). R
a
If a = 5, use the formulas to find the values of b and c.
b
Hence show that (a, b, c) is a Pythagorean triad.
