Pythagorean Theorem and Its Converse

Pythagorean Triple

set of lengths of the sides of a triangle satisfying the converse of the Pythagorean Theorem

a = 5

b = 12

c = 13

CONVERSE OF

PYTHAGOREAN

THEOREM

IF THE SQUARE OF THE LENGTH OF ONE SIDE OF A TRIANGLE EQUALS THE SUM OF THE SQUARES OF THE LENGTHS OF THE OTHER TWO SIDES, THEN THE TRIANGLE IS A RIGHT TRIANGLE.

a = 4

b = sqrt 67

c = 9

a = 8

b = 15

c = 19

a = 10

b = 11

c = 14

Pythagorean Theorem

- In any right triangle, the square of the length of the hypotenuse (c) equals the sum of the squares of the lengths of the legs (a and b). In symbols .

a = 3

b = 4

c = 5

a = 27

b = 36

c = 45

a = 6

b = 8

c = 10

a = 5

b = 12

c = 13

a = 9

b = 12

c = 15

Am I a Right Triangle?

a = 18

b = 24

c = 30
