Question

Determine whether 120cm, 50cm, 130cm can be the sides of a right triangle or not.
​

Answer 1

$\huge \fbox \purple{❥ Answer}$

To prove if a triangle is a right angle triangle, we will use Pythagoras Theorem.

Two of the shorter sides are "a" and "b" and the longest side, the hypotenuse, the "c". If a² + b² = c², then it is a right angle triangle.

Prove:

a² + b² = 60² + 50²

a² + b² = 6100

√6100 = 78.1 cm ≠ c

⇒ It is not a right angle triangle.
