Pythagorea n Triples Beat the Computer Drill Becky Afghani, LBUSD Math Curriculum Office, 2004
What are Pythagorean Triples? Three integers that make the equation a2 + b2 = c2 true are
called Pythagorean Triples. The numbers 3, 4 and 5 are a very famous Pythagorean Triple. a 2 + b2 = c2
32 + 4 2 = 5 2 9 + 16 = 25 Becky Afghani, LBUSD Math Curriculum Office, 2004 Why Memorize
Pythagorean Triples? Remember how much time it took to figure out 8 x 8 before you memorized it? (8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 = 64)
Think of all the work involved to solve this problem: Wouldnt it be nice to just know
this is 5? a2 + b2 = c2 32 + 42 = x2 9 + 16 = x2
25 = x2 5=x Becky Afghani, LBUSD Math Curriculum Office, 2004
Good Pythagorean Triples to Memorize: And multiples
of each, like: 3x2, 4x2, 5x2 6

The following slides show common Pythagorean Triples. It is faster to recognize these triples on sight than to apply the Pythagorean Theorem. When the right triangle appears,
SAY ALOUD the length of the missing side. Try to beat the computer by saying the answer BEFORE it appears in 8 seconds. Becky Afghani, LBUSD Math Curriculum Office, 2004
