If you drive 9 miles north from your house, then turn and drive 12 miles east, you can use the Pythagorean theorem to calculate that you wind up 15 miles from home. You don't need a graph at all to do that. You just have to know the Pythagorean theorem.
3 4 5 6 8 10 9 40 41 20 21 29 9 12 15 ...and factors of those such as the first 2 examples.
3 It is 12 more than -9 and 12 less than 15 9 + 15 = 24 24/2 = 12 -9 + 12 = 3 15 - 12 = 3
5 m. Using Pythagoras: Hypotenuse2 = side2 + other_side2 ⇒ Hypotenuse = √(side2 + other_side2) = √((3 m)2 + (4 m)2) = √(9 m2 + 16 m2) = √(25 m2) = 5 m 3, 4, 5 is a well known Pythagorean triple - the three sides of a right angle triangle (32 + 42 = 9 + 16 = 25 = 52) Another is: 5, 12, 13 (52 + 122 = 25 + 144 = 169 = 132) If you multiply each of these sides by the same number (that is scale the triangle) you get other Pythagorean triples, eg 3, 4, 5 → (x2) 6, 8, 10; (x3) 9, 12, 15; (x4) 12, 16, 20; etc are all Pythagorean triples 5, 12, 13 → (x2) 10, 24, 26; (x3) 15, 26, 39; (x4) 20, 48, 52; etc are also all Pythagorean triples.
15, since 15*2 = 9*2 + 12*2

The Pythagorean thereom is a^2+b^2=c^2. So, you can tell if they are a Pythagorean triple by seeing if the two smaller numbers squared equal the largest number squared. Example. Are 3,4, and 5 a Pythagorean triple? 3^2= 9. 4^2= 16. 5^2= 25. 9+16=25, so they are a triple.
Yes they do. We find this by applying the pythagorean theorum. Since 9^2 + 12^2 = 15^2, they form a right triangle.
3-4-5 is the simplest Pythagorean Triple. Multiply by 3 and you get 9-12-15 which describes your stage exactly.

Indeed they do, it is a Pythagorean Triple: 6*6 + 8*8 = 10*10. (62 + 82 = 102, 36 + 68 = 100, 100 = 100) The "basic" Pythagorean Triple of a 3, 4, 5 triangle works out like this: 32 + 42 = 52 9 + 16 = 25 25 = 25 Your triangle, the 6, 8, 10, figure, is a "doubling" of the cited "basic" triple, and any multiple of a Pythagorean Triple will also be another Pythagorean Triple, and a right triangle.
The straight line distance between 9 miles west and 12 miles south is the hypotenuse of a right triangle with sides 9 and 12. Using the Pythagorean theorem, the distance would be √(9^2 + 12^2) = √(81 + 144) = √225 = 15 miles.
Yes; for example (9, 12, 15) can not be found. However, all primitive triples are found.
A Pythagorean triple is a group of three whole number which can be the sides of a right angled triangle, eg: (3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41), (11, 60, 61), (12, 35, 37), (13, 84, 85), (16, 63, 65), (20, 21, 29), (28, 45, 53), (33, 56, 65), (36, 77, 85), (39, 80, 89), (48, 55, 73), (65, 72, 97)
