sides of this given triangle.
2. If you have the Pythagorean triple (3,4,5), explain how you would generate 5
other Pythagorean triples starting with this one.
3. Suppose that you have two positive integers m and n with m < n. Show that
(n2 − m2 , 2mn, n2 + m2 ) is a Pythagorean triple. Generate all the examples that
exist with 0 < n < 4.
4. Do Problem 15 in section 4.1 of Burger and Starbird.
