Given:
a = 7
b = 9
c = 15
If this is a right triangle c would the hypotenuse
by Pythagorean theorem
where the hypotenuse or c = [tex] \sqrt{a^2+b^2} [/tex]
[tex]c = \sqrt{7^2+9^2} [/tex]
[tex]c = \sqrt{130} [/tex]
since c was [tex]\sqrt{130} [/tex]and not equal to 15 the triangle is not a right triangle.
