Question

Is a triangle with sides of 6 cm, 9 cm, and 16 cm a right triangle? Why or why not?

Answer 1

Yes because it will have a 90 degree angle in it

Answer 2

no

Explanation:

The length of any side of a triangle cannot exceed the sum of the lengths of the other two sides. ... Therefore, if two sides have length 6 cm and 9 cm, the third side has length between 9–6 = 3 cm and 9+6 = 15 cm.
